Ha ha ha. Very funny.

It's not a pop song, the one I'm trying to find. More like industrial/electronic or something. It starts (or ends? don't recall) with graffiti on a wall of the people who made it (CG artists or the band, not sure). The video follows this odly animated character with a hoodie over his head as he walks down this corridor, coming upon a TV mounted high on the wall, on an arm. Then the TV goes bezerk, he starts flailing his arms trying to fend off things unseen - one thinks psychological problems, manifesting as flies buzzing around the guy, but that impression is only from how he flails his arms around. Anyway, then he starts running back down the corridor, with the glowing tv after him. He exists the corridor into a larger, high-ceilinged room with pillars scattered around (kinda like the Balrog's vault in LOTR, just on a far smaller scale), and when we next see the TV, it's grown to enormous proportions.
Oh yeah, and ignore what I said about the TV chasing the camera's POV - it's chasing the guy the whole time.
...no bells, eh?
