Def Jam artist Jeremih, the only singer on this list, emerged to fame in 2009, with his popular slow jam 'Birthday Sex,' an R&B chart topper. Since then, he's released two studio albums 'Jeremih' in 2009 and 'All About You' in 2010.

The Chicago crooner has been taking his time with his third LP, '773 Love' and released his first-ever mixtape 'Late Nights' in August 2012. With 18 cuts, the project features from Fabolous, 2 Chainz, Gucci Mane, Natasha Mosely and others.

Jeremih turns the lights down low as he whispers -- often in Auto-Tune -- dirty talk about how his mojo is top-notch. On '773 Love,' he brags, "I can be your occupation, work you like a 9 to 5, just put in the overtime." The tape was a welcomed effort for R&B and rap fans alike.
