I use Google Translate to help me with Japanese CD listings. It works pretty good for the most part. It also gives you a romanji translation which is pretty accurate. The English translation needs some work though. I tried to translate a song title from my Gunbuster soundtrack. The title was:
いけいけぼくらのガンバスター!! (TVサイズ カラオケ)
Google came up with a pretty good romanji translation:
Ike ike boku-ra no ganbasutā! ! (TV saizu karaoke)
My best guess is:
Go! Go! Our Gunbuster! (TV size karaoke)
Google came up with:
Gamba star of our bitch!! (TV size karaoke)
Which is pretty interesting.
