Day 11: A song on the soundtrack of your favourite movie.
I have waaaayyyy too many favourite movies, but the first thing that came to mind was this:
Black Sheep--The Clash at Demonhead. Scott Pilgrim vs. The World Soundtrack. I prefer the version with Brie Larson's vocal, even though it is technically a song by the band Metric.
Day 12: The last song you heard.
I believe it may have been this:
Birthday Cake--Cibo Matto. I blame Jet Set Radio Future.
