Ryuichi's J-pop Music Station My favorite translations site. He has lots of Speed, Zard, L'arc en Ciel translations, as well as all of Utada Hikaru's First Love album translations (if you see other sites with the same translations, just know they came from his site), + tons of others...definitely a must-see!!! Also has guitar tabs, some movie reviews, etc. Updates the beginning of every month, but takes no requests anymore.
(NEW) ambivalences.net Formerly known as "Yume no Ato." Translations of The Brilliant Green, Mizuki Nana, Sasaki Yuuko, and other artists.
(NEW) Angel Egg A great romaji (& sometimes translation) site. Heidi has mostly anime lyrics here, but it's worth a look. A lot of lyrics from artists/anime like ALI PROJECT, DI GI CHARAT, I'VE, KOTOKO, & LIA to name a few.
The Anime Fanboy This is an old site, but I recently re-discovered it (many url changes=bad). I like it a lot because the webmaster explains what his thoughts are, plus the format is interesting. Too bad he quit updating almost 3 years ago.
(NEW) Anime Lyrics.com This was originally Sailor Bacon's site, but nowadays most of the lyrics are done by contributors. I can't believe that I didn't add this one earlier..it's probably the most well known lyric site on the net.
BOBMINK STYLE They have a few song translations here + translations of some manga as well.

Campus Lyrics Lots of anime lyrics + some hitomi translations as well. ^^
Centigrade-J Another excellent translations site, but it doesn't have the romaji. I like that Brian & Takako explain what the song's about at the end of each translation. This site also has some reviews, news about some artists, and some translated articles. Check it out! Takes translations requests.

Megchan no Shumi A lot of great translations here including tons of Morning Musume related stuff, some current hits, etc. though she doesn't update as often as before. Also has a trading section, etc. Takes translations requests if she has the lyrics (See her romaji section).
(NEW) Mitsuketa Lyrics A fairly new romaji lyrics site. They focus somewhat on less popular artists. (ROMAJI ONLY)

Moonless Triton Amai, Amai...what happened to your site?? It was one of the sites that I directed to when I didn't have a certain translation on my site. Lemme know if/when you ever get it back up, ok?
