For some reason, this makes me extremely happy:
Without any ranking, it is awesome because (of):
2) The fact that the original is a pretty good song by itself.
3) They performed their own spin on it shortly after listening to it for the first time.
4) They look like they are enjoying themselves.
5) They are jamming nicely together.
6) The ring tone at the end.
7) How they are all swaying left and right (Can’t help doing it while listening to it too!)
