Ah....I don't listen to American music anymore, it's all Japanese music in my CD case!
But, I prefef guys than girls. It seems to me that (in Japanese music) girl bands break up faster than guy bands. For example, there's this girl band in Japan called SPEED and they basically sing pop music. I only got their albums, 'cause they were the most popular girl band at the time, and I was new and naive to Japanese music. But, they broke up 'cause they wanted to go solo. I agree with Cannibal, I don't think Japanese girls (or guys) should sing rap. Omigod....my ears. One of the members in that SPEED group loves everything to do with blacks; she's got the long nails, the braided-hair, the attitude...don't get me wrong, I'm not a racist, I just don't think Asians should try to be black 'cause it's embarrasing, especially if they've got an accent. But, I listen to guy bands and they're not exactly pop or boy bands, 'cause I listen to Japanese Rock (J-Rock) and it's slightly mixed with Japanese Pop. But, I love GLAY, Aucifer, SMAP, Judy and Mary, and a few others....can't think of them right now.
