Keyshia, Ne-Yo, Alicia, Rihanna, Kanye many of those albums are incredible to my ears.
I don't care what anyone says "As I Am" it's great musically and lyrically.
The last artist on the list needs no introduction. He has been hated on, but still one of the most wanted artist of 2007. He hit the scene with his debut single "Crank That". "Soulja Boy up in this hoe, watch me crank and watch me roll, watch me crank that soulja boy then superman dat hoe". The song managed to sell over 2M downloads in just a half of a year, beating out songs that have been selling for months. Soulja Boy's debut album actually sold, you know why, because every song on that album is likeable in some way. Soulja Boy is truly the top breakthrough artist of 2007!
