Namie's music in general isn't that bad, but you really have to be a fan of '90s techno-pop (for her first works) or Western hip-hop and R&B (for some of her later albums) to like it. Otherwise, it's pretty boring.
However, I think STYLE is a great album, probably because it's a perfect mix of J-Pop and Western hip-hop/R&B. I think it's her best album, by far. (Though, for those that don't know, a few of the songs on there are covers, including Come.) Her second best album would be PAST>FUTURE. It's another very J-Pop album, though, with not much Western hip-hop, so maybe that's why I find it better..... Queen Of Hip-Pop is a pretty good album, too, if that's your style.. It's not really mine, but I think WANT ME WANT ME is a great song.
