Vocally, Nami is acceptable but nothing special; She also doesn't really seem to dance, so apparently She's marketed mostly for Her looks, which is fine. This single comes with "IAM" (not spaced as it is listed on Amazon), "Balance" and karoke versions of both. Also comes with a sexy but conventional video. As Top 40 dance/light rock numbers go, this is okay stuff, but you have to be committed to pay Japanese prices for these discs. Basically, it's worth it if you look at that cover and think, "HOT."
