The year has ended with a flourish of high-profile collaborations from top country music stars. Jason Aldean pulled two of the hottest males artists in Nashville into the same room to record 'The Only Way I Know' in 2012, while Kelly Clarkson convinced Vince Gill to lend his voice and guitar to 'Don't Rush.' These are the most recent, but hardly the only collaborations from the banner year.

Also included in today's readers poll is Tim McGraw and Kenny Chesney's work on 'Feel Like a Rock Star,' Taylor Swift's pairing with pop singer Ed Sheeran for 'Everything Has Changed,' Willie Nelson and friends on 'Roll Me Up ...' and Colt Ford's cut with Jake Owen.
