(I don't like that cheezy sounding Arashi stuff)
Does anybody here listen to DBSK/TVXQ/Tohoshinki, as they're known in Japan? They're Korean, and they sing hip hop/R&B. They're really good (and also really popular in Japan nowadays). They have lots of great music, both Korean and Japanese. I think you might possibly like them, Nick? Maybe? Unlike Johnny's *cough*, they're all really talented singers and dancers. I can rec specific songs if you want. And, um, I know they're Johnny's and all, but KAT-TUN has some songs you might possibly like, like Don't U Ever Stop. They're the most musically "edgy" Johnny's group, with mostly hip-hop/R&B/rock songs.
I personally mostly listen to j-rock (when I'm not listening to Johnny's music...). I have about a million favorite bands, including, but not limited to: Aqua Timez, UVERworld, Asian Kung-fu Generation, Orange Range (I'll call them j-rock even though they seem to cover a bunch of...weird...genres), One OK Rock, Ellegarden (one of my all-time favorites, with English that actually sounds like English!), Stereopony (awesome girl band!), flumpool (pretty popular as of late), GReeeeN, and No Regret Life.
Some female vocalists I like (when I listen to them, lol) are Ito Yuna, Yui (everyone likes her), Wakeshima Kanon, alan, Kiroro, Abe Mao, and Ayaka (freaking lucky girl, married to Mizushima Hiro).
...And I have rambled on plently long enough now. My bad. I get excited about this kind of stuff, lol. Brian was right.
