What do I do if a MP3 file from MusicMatch (or a secondary source) doesn play?
It is possible that a file name of the MP3 file is too long or contains incompatible characters. If you have a problem with the transfer or playback of MP3 files with very long names, try making them shorter than 45 characters long. Some MP3 files created using unusual MusicMatch options have a compatibility problem with numerous devices. Visit the MusicMatch FAQ for details. If you are downloading or converting MP3’s in MusicMatch Jukebox, you should choose the following.
