naruto has come out already with animemp3, aost, ago, nipponsei, vga, and O-A (OSTs I and II are distributed amongst them)
bakuretsu tenshi has yet to come out, if i'm not mistaken
KMUS has come out with nipponsei
KBSMDB has yet to come out
Melody of Oblivion has yet to come out

I'm pretty sure KoBJ has come out, since it's an old series.

the key to a lot of these series is to be patient. the tracks will eventually come out, especially with series currently being released.

If you're that desperate, just go look up what the track titles are in the anime and go find them in IRC.
