The Music Meet Up is back! New week means new songs and I've got some powerhouses for you tonight. Sia latest, in support of the new motion picture Music, 'Together' is definitely that upbeat, fun track you'll want to dance around the house to. She's up against Sofia Carson and R3HAB's 'Miss U More Than U Know'. The perfect summer banger that needs to be on your playlist if it isn't already. Two songs enter the ring. One goes home. And it's all up to you. Hit the tweet below, place your vote and we'll see who's going on to tomorrow night!
