Why: On the surface it seems that, much like Quebe Sisters, the Zac Brown Band simply benefit from being one of very few artists who fall under their letter in the alphabet. But two Platinum albums and over 10 Top 5 hits make the 'Chicken Fried' hitmakers a tough act to top, Z or no Z. The Georgia-based band has earned their letter as a viable band on the radio and a can't-miss act on the road.

Honorable Mention: Zaca Creek
