Sonic Drive-In Signature Slingers TV Spot, 'CMT: New Song Flavor'

CMT's Music City cast members Jessica, Kerry and Alisa take a break from the studio and head to Sonic for some Signature Slingers. Jessica admits that her new song could use a little flavor and is pleasantly surprised how good her Signature Slinger is. With all the flavor and none of the guilt, Kerry thinks that there's definitely a song in the making. Sonic's Signature Slingers, featuring a patty made with beef, mushrooms and seasonings, are available for a limited time at the restaurant.
