Being a bit of an anime geek I have a bunch of soundtrack CDs from Japan. iTunes handles them just wonderfully. Even CDDB seems to have pretty good results (many times in japanese). But every once in a while I run into a CD where the information in CDDB is in some strange character set that I can't identify. When this happens I usually check over on FreeDB.org to see if they have better information (which they do much of the time). Today I discovered some great scripts for managing my track listings and looking them up on FreeDB.
Dave's AppleScripts for iTunes has tons of useful scripts. I found one called something like FreeDB to iTunes via Safari that worked amazingly. It pulls the tracklisting from a FreeDB page and pastes it into iTunes.
Though what I'd really like is for iTunes to support using FreeDB, since they seem to be a big fan of open source projects.
