I saw 'Comedy' in the genre, so I sort of assumed that this would be making fun of Justin Bieber (like a parody of sorts) to TGWLTT.
'Guess I shouldn't have really assumed. ^^;
I'm really against anything Bieber, so it was alright. Parts didn't really fit at the beginning too well with the lyrics (by the second verse they did, I found).
Also the second chorus of 'Baby' was kind of edited in an anti-climactic way. You synced a few beats before it, but there were a few more, and then suddenly you left the rest of the beats and the chorus to one slow-mo scene.
Found that kind of odd.
But a decent edit anyways.
