- IMHO file names should never ever contain anything else but only “printable ASCII” characters.
- letting music file names reflect the contents is sometimes just too much work, so sometimes I abbreviate them to just the track number
I just came across some Glenn Gould albums, and now the file names all look like 99.mp3. I first tried something better than that, but that was just PITA and I stopped it. I did improve and clean the track names themselves though. Maybe they are too long for the iPod now, but they display well in iTunes.
