It doesn't. Music player holds a partial wake lock which keeps the CPU running when the screen is off. It is important to note: (device sleep) != (screen off). Holding a partial wake lock has a negative impact on battery life. Depending on the process holding the wake lock and the other processes running on the phone, the wake lock can have a detrimental impact on battery life.
In the case of music player, it is apparent that the users wishes to trade battery life for a purpose (playing music). Use wake locks *very* carefully.
