I have an mp3 player in my car.
I want to order the songs I burn on my CD.
Currently, the player reads them in alphabetical order.
Does this depend on the mp3 player type (I don't think so).
It seems to me like the only way of doing so is adding a prefix with a
number to the song, in order to sort them in alphabetical order. There
is no notion of a track, as in a "regular" classic CD.

Furthermore, is there a limitation on the characters being used?
Is it possible to use other character sets than English?
If so, does the player has to support them?
