>Yupp, as the title is shown in the car it must be encoded on CD as well. Have never really looked into that, but probably lots of tools exist that can automatically set correct (song)file names. For the rest there HAS to be some online database to scrape ;-)

There is. My Qmmp player checks it whenever I doubleclick a song title with incomplete data. You'd be surprised how fast that works, even o my low speed net and how many obscure bands are well covered.
