See this link. Go to 3:10 position. Also 3:22 because may be it is different song.
It is the introduction video of Apple's WWDC 2015 keynote presentation. I love that song and I've tried to find it but I couldn't.
It seems very much like the whole thing is written specially as part of the sketch, including both the rap at 3:10 and the song at 3.22, which both have lyrics referencing apple products:
The only place I could find the lyrics on the web are here, which is a script for this sketch.
David, Why did I want to direct the WWDC opening number?
You know, I think I've always been attracted to risk.
When I shared my vision for the number, um, you know, they said,
Hey, this is just a developer's conference, you know.
you don't need to overthink it.
but I always feel that my job as a director
is to push an idea.
What's that? Am I a genius?
I don't know -- What?
Stage Manager: Hey David, you ready for the walkthrough?
Stage Manager: Who are you talking to in here?
David: No one. Shh.
Stage Manager: You were talking to somebody,
unless you were talking to yourself.
Dana: I've been working on this new app called "Work Crush."
It's for people who have crushes on their workmates
and want to know when they're nearby.
It's not for me, but... PHONE CHIMES
Oh, hi David!
David: Yeah, I thought you were supposed
to be guarding my door.
Dana: Which one's your door?
David: What is this? Rick! Rick, look at me.
I need you angry in there, Rick.
I need you angry, angry, angry!
Alright, did you get that email about my email not working?
David: What? No, no, no!
It needs to be more, you know, like WHOOSH!
Dana: Yeah, he means bigger.
David: Bigger, bigger, yeah, like developers are on fire!
Runner: Which iPhone do you want for the main character,
silver or gold?
David: Let me see silver.
Let me see gold.
Let me see silver.
Let me see gold.
See I can't tell because
the reflection of the flame is on it,
and I can't ...
Fire Marshall: Can you decide this later?
David: Yeah, he's right. Let's decide it later.
Dana: We'll take the gold.
Got to choose the talent for the dating app number.
The pretty one.
Runner: That's you.
Did you do this?
David: Oh my gosh, that's my coffee!
David: Oh, cool!
Oh, that's awesome.
Did you bring my sugar or anything?
Who are these guys?
Dana: The Tim Cook-a-likes you asked for.
David: Oh, right.
Hey, you guys are good to get wet, right?
David: Oh, hey, you guys are the faces of WWDC.
Let's give it all.
Well, not the real faces,
you're the masks that they give you.
Dana: Goat Simulator.
David: Goat Simulator, I'm not feeling it, kill it.
Alright ... Oh, that's an axe!
No, no, no, don't ... Don't actually kill it, okay?
There he is! Hey!
Angel Investor: David, what have you got me into here?
Am I like a Victoria's Secrets guy?
David: You are an angel investor.
You make millions off kids' dreams.
Angel Investor: So I'm just a rich guy?
David: You're a rich guy.
Bring him up!
Angel Investor: This harness cuts the circulation off
in my legs.
David: Oh, that's alright buddy, no worries.
Choreographer: OK, let's run it.
David: No, no, no, I say when we run it.
Who is that? Why is he saying my words?
Choreographer: Run it. David: Thank you.
