Although my favourite group at the moment is EXO, I generally prefer girl groups. For some reason, I like listening to female singers more and I find girl group concepts and costumes more appealing and nicer to look at than baggy hip-hop-clothes or stereotypical boy wear. I also have the impression that a lot of boy group songs contain heavy rap or weird melodies or maybe I've listened to the wrong kind of groups… But when it comes to choreographies, I definitely prefer boy groups. :o
