So you’ve probably all seen this student-made spot from the UK for iPod Touch, featuring Cansei de ser Sexy’s “Music is my Hot, Hot Sex.

It’s a fine piece of editing, but when I saw it, I thought, heck, all he REALLY did was pick an awesome song and time some animations. Big deal, right?

Here’s the irony: a year ago, Microsoft had a ZUNE spot running with the SAME SONG.

What’s the moral of this story? Well, the amateur kid kept it simple: Music = HERO. Interface = Easiest way ever to hang with HERO. In the Zune spot, the song is part of a schizophrenic execution that’s trying to: a) be irreverent with stylized, anthropomorphized illustrated animals b) cycle through a list features (music, wireless, tuner, community) c) bring it all back to music and “social” by building a narrative.

Wow, that’s a lot. Just listening to a Brazilian girl sing “Music is my Boyfriend, Music is my Girlfriend” seems to sum all that up, with like, 1/1000th of the work. It’s just an ironic slap in the face that they had the perfect weapon (the song) and didn’t know how to use it properly.

Just found more assessments of the two spots.
