I saw that the line has <track name=""></track>
but I could not put the MP3 file, the emulator hangs

try .wma

Yeah, it has to be .wma files. It won't read mp3s. I'm not certain but the bitrate of the .wma tracks may have to be 64kbps too. May be totally wrong about that part but you'll get good compression at that rate with no noticable loss in sound quality.

It should look like this in the config.xml:

<!-- Music for this category -->
<track name="CPS1">CPS1.wma</track>

You can call the track anything you want of course though.
