This could've been so much better!
Okay, first of all, everyone, this song is PACHELBEL'S CANON. It's a famous classical piece that dates back over 300 years.
The biggest problem is the audio and video sync. The entire animation is sprites carefully (read: not carefully enough) synced to each of the musical notes.... but it doesn't really work out that way. The bongos at the end are terrible, and I think a different background besides boring gray would have been better.
