This is the song that got me into the band, because it was in Scott Pilgrim Vs. The World for 2 seconds and that landed its full version onto the soundtrack. Broken Social Scene is pretty great, as is Metric (the main band of this song's original vocalist, Emily Haines). In the words of the great John Allison, BSS sounds like "someone has sat on the mixing desk and messed up all the faders."
I was originally going to sing this one myself, but my friend Amy wanted to lend her beautiful voice to the project.
