Apparently the Zac Brown Band and Shawn Mendes love goes beyond CMT Crossroads!
ZBB released their new song, "Someone I Used To Know", and Shawn actually helped write it!
They performed it on The Tonight Show the other night, and they also announced that they'll be touring this Spring.
It's definitely not the typical ZBB we've (home)grown to love, but damnnnn I like this sound A LOT!!!
