He may be a big-time country star. But Blake Shelton turns to other genres of music when it comes to choosing the ringtones for his phone. He tells Entertainment Weekly that his current ringtone is "Back in Black" by AC/DC. And before that, he swung from heavy metal to pop when he chose "Rich Girl" by Hall & Oates. His girlfriend Miranda Lambert opts for Beyonce's "Irreplaceable" -- and Shelton says whenever he's around when she gets a call, he "can't help but dance."
