The chart run of this song isn't really outstanding, but it is so memorable for me this year because my friends, cousins and I used to jam to it a lot.

This song is no exception to his string of awesome collaborations. I remember having a bad case of last-song-syndrome with this one.

Usher had a big year this year, he had two really successful single, both of which are dancefloor anthems. DJGUFIL is the first one, and the other is coming up really soon.
PARAMORE
CAREFUL
Brand New Eyes

Ironically, I find this song as one of their weakest single ever, but I also find it as one of the strongest album tracks. I dunno, its weird.
MIRANDA COSGROVE
KISSIN' U
Sparks Fly
Day/s: 22 | Peak: 01[2]
Such a cute little song from cute little girl. Undeniably my biggest guilty pleasure of the year.
Top 25 is up next. I'm not spilling and disclosing any information this time. You either have to wait, or give up guessing.
