The other day, I made an mp3 CD for my car stereo. The iTunes playlist was a combination of all my Japanese music, most of which have titles in Japanese. When the titles come up on the car stereo, they have file names like 10.mp3 or 15.mp3. I also noticed that a English title 777-9311 shows up as _777-9311.mp3. Am I right to assume that the mp3 file naming conventions are about those of CP/M? The first character must be alphabetic with certain exceptions and the other characters must conform to the ASCII character set? Thanks for your help!
