In no particular order...
"Pretty Girl Rock"-Keri Hilson; Ok, maybe not one of the best from the year, but it's in my head!
"Lil Freak"-Usher Ft Nicki Manaj, I had to get Nicki in here, she has had a huge impact on the RnB/hip hop world this year!
"Sex Intelligent"-The Dream
"Find Your Love"-Drake
I love this video...not to mention the song!! Chad Michael Murray and Alicia=Love...not to mention probably the cutest baby ever, sorry Swizz Beatz but they should get on it ;)
