Every now and then you discover a song that's so infectious it can drive an artist from relative obscurity to fame. Flo Rida's 'Low' fits the bill. The Florida-based rapper's debut, 'Mail On Sunday' -- in stores today -- features all the usual suspects, including Lil Wayne, T-Pain, Will.i.am and Timbaland, to name a few.

At the other end of the spectrum is Sheek Louch's 'Silverback Gorilla,' which also hits stores today. Unlike newcomer Flo Rida, Sheek's days on the microphone date back to 1995 as one-third of the LOX. The Yonkers, New York, emcee continues to rep D-block while delivering a more commercial sound with the album's first single, 'Good Love.'
