I've always enjoyed collaborations and vocal event projects in Country Music. From the Highwaymen with Willie Nelson, Waylon Jennings, Johnny Cash and Kris Kristofferson to Tracy Lawrence, Tim McGraw and Kenny Chesney's smash 'Find Out Who Your Friends Are.'

Over the last few months we've heard some great collaborations on Country Radio for 2013. In case you didn't know, here's who's helping each other out on these current hit songs.

The Only Way I Know- Jason Aldean, Luke Bryan, Eric Church

Don't Rush- Kelly Clarkson and Vince Gill

Highway Don't Care- Tim McGraw, Taylor Swift and Keith Urban on guitar

Wagon Wheel- Darius Rucker and Lady Antebellum
