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.

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.
