yes it's mostly because of the 1D rivalry thing, but tw are really sweet and attentive to all their fans and they've had 2 solid pop albums and an amazing EP. I'd check their music out if I were you.

If you're looking for a great ballad give "warzone" a listen. "Lose my mind" has a slight 90's boyband feel to it, and of course you have their more clubbish songs like Glad You Came and Chasing the Sun
