There's liner notes on a good few albums that I'd love to see translated (or even just put into Japanese text, so lesser individuals like myself can use altavista or whatever), but I imagine that's quite a big job, and unfortunately not something I'd know how to do.
As for tracklists, right now I'd be most interested in seeing translations of
Ganbare Goemon: Yukihime Kyushutsu Emaki and
MCMXCI. There are probably others that I can't remember at the moment.
