This one is called "Someone's Watching" which is from "The App" which is an Alvin! And The Chipmunks episode on Nick on TV. It's for The Lego Movie about Wyldstyle/Lucy being watched by Octan before she became a master builder and looked for The Piece Of Resistance.
Wyldstyle/Lucy:"Don't tell me you're gonna be on my tail ALL the time!"
Octan:"24/7."
Wyldstyle/Lucy:(Groaning)"Oh..."
Octan
Everywhere you look, everywhere you turn, I'll be watching you
Wyldstyle/Lucy
You're watching my every move
You're trying to tell me what to do
I see you (ah ha, ah ha)
I see you (ah ha, ah ha)
You're the shadow I can't shake off
Please back off, you should take off
I see you (ah ha, ah ha)
I see you (ah ha, ah ha)
Wyldstyle/Lucy (Octan)
Everywhere I look (everywhere you look)
Everywhere I turn (everywhere you turn)
You're spying on me (I'll be watching you)
I feel your eyes on the back of my neck
With every step, with every step I take
Someone's watching, I wish you would back off of me
Someone's watching, you're so close that I can't breathe
Someone's watching, everything I do you see
I see you watchin', I see you watchin' me
Octan
I-I-I, I'll be watching you, watch-watching you
