They are definately a boy band, but make it look like they're a rock band by jumping about with guitars. There's no way they can all play guitar on the same song, plus what about Bass and Drums, and maybe even keyboards in a couple of the tracks? All the music is done by synthesizers and the guitars are just there for show. Their songs are written by some professional song writing team, and don't make sense, plus all they do is sing. Pretty crap in my opinion, but I suppose some of the songs sound catchy, and that's why they sell. I hate most modern chart music for these reasons.
