Sorry about the quality... I can't afford better plugins yet, and also some of the notes had to be shifted by an awful lot (which is why I didn't put autotune... a lot of this was manual work). No offense, OAG. Great job on your video by the way. The expressions you make are hilarious.
Oh, also, if I got the melody wrong at some point... woops. I've actually only heard this song a few times, and I did it from memory since I was trying to go as fast as possible.
EDIT: To clarify, I am not OAG. I just tuned her original video and thought other people might like to hear that version.
