Often when an artist drops one record label, he or she struggles to find another. Sometimes, stars find out that fans and especially radio have grown a little tired of them, and they're less receptive to projects from the new label. Today's poll question includes artists who switched labels or simply disappeared for a few years, but are now back and perhaps better than ever. Who is your favorite comeback artist of 2012? 

Love and Theft released a critically-acclaimed new CD two years after losing a deal with Lyric Street Records. Alan Jackson and Chris Cagle also switched teams before releasing new projects. In addition, it's been five years since Big and Rich released new music together, and nine years since fans of the Mavericks had something to be excited about.
