at all.

If the first session on the disc is a CD-DA session, the other sessions 

on the disc cannot be recognized regardless of the session format; 

only CD-DA tracks in the first session can be played back.

If the session format for the first session is CD-ROM and the 

following sessions are recorded in the same format, the system will 

continue to play back MP3 files accordingly in multiple sessions 

until the system encounters another session recorded in a different 

format.
