I don't really listen to boy bands or girl bands per se. I listen to whatever is good. If boy bands or girl bands happen to sing it, then well I listen to them.
I think Boy bands have mostly female fans. Girl bands have some boy fans, but I mostly see females listening to them more.
I think pop music have more female fans then boy fans. But, I could be wrong, but when I switch on the TV I mostly see girls holding signs that say `We love the Spice girls``
^well the thing with Boy bands and girl groups is that there's always one lead singer the rest are just back ground noises =/ I dont even see a point in having one. IMO its like "we;re gonna group you girls together because we all know you will never make it big"
