a TED Talk online at one time or another, right?

So what I'm going to do is play this.

This is the song from the TED Talks online.

(Music)

And I'm going to slow it down

because things sound cooler when they're slower.

(Music)

Ken Robinson: Good morning. How are you?

Mark Applebaum: I'm going to -- Kate Stone: -- mix some music.

MA: I'm going to do so in a way that tells a story.

Tod Machover: Something nobody's ever heard before.

KS: I have a crossfader.

Julian Treasure: I call this the mixer.

KS: Two D.J. decks.

Chris Anderson: You turn up the dials, the wheel starts to turn.

Dan Ellsey: I have always loved music.

Michael Tilson Thomas: Is it a melody or a rhythm or a mood or an attitude?

Daniel Wolpert: Feeling everything that's going on inside my body.

Adam Ockelford: In your brain is this amazing musical computer.

MTT: Using computers and synthesizers to create works. It's a language that's still evolving.

And the 21st century.

KR: Turn on the radio. Pop into the discotheque.

You will know what this person is doing: moving to the music.

Mark Ronson: This is my favorite part.

MA: You gotta have doorstops. That's important.

TM: We all love music a great deal.

MTT: Anthems, dance crazes, ballads and marches.

Kirby Ferguson and JT: The remix: It is new music created from old music.

Ryan Holladay: Blend seamlessly.

Kathryn Schulz: And that's how it goes.

MTT: What happens when the music stops?

KS: Yay!

(Applause)

MR: Obviously, I've been watching a lot of TED Talks.

When I was first asked to speak at TED,

I wasn't quite sure what my angle was, at first,

so yeah, I immediately started watching tons of TED Talks,

which is pretty much absolutely

the worst thing that you can do

because you start to go into panic mode, thinking,

I haven't mounted a successful expedition to the North Pole yet.

Neither have I provided electricity

to my village through sheer ingenuity.

In fact, I've pretty much wasted most of my life

DJing in night clubs

and producing pop records.

But I still kept watching the videos,

because I'm a masochist,

and eventually, things like Michael Tilson Thomas

and Tod Machover, and seeing

their visceral passion talking about music,

it definitely stirred something in me,

and I'm a sucker for anyone talking devotedly

about the power of music.

And I started to write down on these little note cards

every time I heard something

that struck a chord in me, pardon the pun,

or something that I thought I could use,

and pretty soon, my studio looked like this,

kind of like a John Nash, "Beautiful Mind" vibe.

The other good thing about watching TED Talks,

when you see a really good one,

you kind of all of a sudden wish the speaker

was your best friend, don't you? Like, just for a day.

They seem like a nice person.

You'd take a bike ride, maybe share an ice cream.

You'd certainly learn a lot.

And every now and then they'd chide you,

when they got frustrated that you couldn't really

keep up with half of the technical things they're banging on about all the time.

But then they'd remember that you're but a mere human

of ordinary, mortal intelligence

that didn't finish university,

and they'd kind of forgive you,

and pet you like the dog.

(Laughter)

Man, yeah, back to the real world,

probably Sir Ken Robinson and I

are not going to end up being best of friends.

He lives all the way in L.A. and I imagine is quite busy,

but through the tools available to me -- technology

and the innate way that I approach making music --

I can sort of bully our existences

into a shared event,

which is sort of what you saw.

I can hear something that I love in a piece of media

and I can co-opt it

and insert myself in that narrative,

or alter it, even.

In a nutshell, that's what I was trying to do

with these things, but more importantly,

that's what the past 30 years of music has been.

That's the major thread.

See, 30 years ago, you had the first digital samplers,

and they changed everything overnight.

All of a sudden, artists could sample

from anything and everything that came before them,

from a snare drum from the Funky Meters,

to a Ron Carter bassline,

the theme to "The Price Is Right."

Albums like De La Soul's "3 Feet High and Rising"

and the Beastie Boys' "Paul's Boutique"

looted from decades of recorded music

to create these sonic, layered masterpieces

that were basically the Sgt. Peppers of their day.

And they weren't sampling these records

because they were too lazy to write their own music.

They weren't sampling these records to cash in on

the familiarity of the original stuff.

To be honest, it was all about sampling

really obscure things,

except for a few obvious exceptions

like Vanilla Ice and "doo doo doo da da doo doo"

that we know about.

But the thing is,

they were sampling those records

because they heard something in that music

that spoke to them

that they instantly wanted to inject themselves

into the narrative of that music.

They heard it, they wanted to be a part of it,

and all of a sudden they found themselves

in possession of the technology to do so,

not much unlike the way the Delta blues

struck a chord with the Stones and the Beatles and Clapton,

and they felt the need to co-opt that music

for the tools of their day.

You know, in music we take something that we love

and we build on it.

I'd like to play a song for you.

(Music: "La Di Da Di" by Doug E. Fresh & Slick Rick)

That's "La Di Da Di" and it's the fifth-most sampled

song of all time.

It's been sampled 547 times.

It was made in 1984 by these two legends of hip-hop,

Slick Rick and Doug E. Fresh,

and the Ray-Ban and Jheri curl look is so strong.

I do hope that comes back soon.

Anyway, this predated the sampling era.

There were no samples in this record,

although I did look up on the Internet last night,

I mean several months ago,

that "La Di Da Di" means, it's an old

Cockney expression from the late 1800s in England,

so maybe a remix with Mrs. Patmore

from "Downton Abbey" coming soon,

or that's for another day.

Doug E. Fresh was the human beat box.

Slick Rick is the voice you hear on the record,

and because of Slick Rick's sing-songy,

super-catchy vocals, it provides endless sound bites

and samples for future pop records.

That was 1984.

This is me in 1984, in case you were wondering

how I was doing, thank you for asking.

It's Throwback Thursday already.

I was involved in a heavy love affair

with the music of Duran Duran,

as you can probably tell from my outfit.

I was in the middle.

And the simplest way that I knew

how to co-opt myself into that experience

of wanting to be in that song somehow

was to just get a band together of fellow nine-year-olds

and play "Wild Boys" at the school talent show.

So that's what we did, and long story short,

we were booed off the stage,

and if you ever have a chance to live your life

escaping hearing the sound of an auditorium

full of second- and third-graders booing,

I would highly recommend it. It's not really fun.

But it didn't really matter,

because what I wanted somehow

was to just be in the history of that song for a minute.

I didn't care who liked it.

I just loved it, and I thought I could put myself in there.

Over the next 10 years, "La Di Da Di"

continues to be sampled by countless records,

ending up on massive hits like "Here Comes the Hotstepper"

and "I Wanna Sex You Up."

Snoop Doggy Dogg covers this song

on his debut album "Doggystyle" and calls it "Lodi Dodi."

Copyright lawyers are having a field day at this point.

And then you fast forward to 1997,

and the Notorious B.I.G., or Biggie,

reinterprets "La Di Da Di"

on his number one hit called "Hypnotize,"

which I will play a little bit of

and I will play you a little bit of the Slick Rick

to show you where they got it from.

(Music: "Hypnotize" by The Notorious B.I.G.)

So Biggie was killed

weeks before that song made it to number one,

in one of the great tragedies of the hip-hop era,

but he would have been 13 years old

and very much alive when "La Di Da Di" first came out,

and as a young boy

growing up in Brooklyn,

it's hard not to think that that song probably held

some fond memories for him.

But the way he interpreted it, as you hear,

is completely his own.

He flips it, makes it,

there's nothing pastiche whatsoever about it.

It's thoroughly modern Biggie.

I had to make that joke in this room,

because you would be the only people that I'd ever have a chance of getting it.

And so, it's a groaner. (Laughter)

Elsewhere in the pop and rap world,

we're going a little bit sample-crazy.

We're getting away from the obscure samples that we were doing,

and all of a sudden everyone's taking

these massive '80s tunes like Bowie, "Let's Dance,"

and all these disco records, and just rapping on them.

These records don't really age that well.

You don't hear them now, because they borrowed

from an era that was too steeped

in its own connotation.

You can't just hijack nostalgia wholesale.

It leaves the listener feeling sickly.

You have to take an element of those things

and then bring something fresh and new to it,

which was something that I learned

when I was working with the late,

amazing Amy Winehouse

on her album "Back to Black."

A lot of fuss was made about the sonic of the album

that myself and Salaam Remi, the other producer,

achieved, how we captured this long-lost sound,

but without the very, very 21st-century personality

and firebrand that was Amy Winehouse and her lyrics about rehab and Roger Moore

and even a mention of Slick Rick,

the whole thing would have run the risk

of being very pastiche, to be honest.

Imagine any other singer from that era over it

singing the same old lyrics.

It runs a risk of being completely bland.

I mean, there was no doubt that Amy

and I and Salaam all had this love

for this gospel, soul and blues and jazz

that was evident listening to the musical arrangements.

She brought the ingredients that made it urgent and of the time.

So if we come all the way up to the present day now,

the cultural tour de force that is Miley Cyrus,

she reinterprets "La Di Da Di" completely for her generation,

and we'll take a listen to the Slick Rick part

and then see how she sort of flipped it.

(Music: "La Di Da Di" by Slick Rick & Doug E. Fresh)

(Music: "We Can't Stop" by Miley Cyrus)

So Miley Cyrus,

who wasn't even born yet when "La Di Da Di" was made,

and neither were any of the co-writers on the song,

has found this song that somehow

etched its way into the collective consciousness of pop music,

and now, with its timeless playfulness of the original,
