If you think a little, a lot of pop music can easily turn into metal if arranged differently and the same happens for some metal songs. You can easily turn a Metallica song into a lounge-type song if you want or you can make Britney sound like speed metal. I don't really think you should bother. You should just focus on playing good music, music that you feel you really like and you stand up to it, regardless of what label it has. If the music does bother you, just leave the band and search for something that suits your needs.
