Your music player software doesn't need to care about Bluetooth. That's part of the operating system you're using -whatever that might be, you forget to tell us.
All your application needs to do is play music and react to the operating system telling it about media control events. How these are exchanged between programs and operating system really depends on the operating system and in which framework you're programming. Some systems, these button presses are converted into virtual keyboard presses. Other os/framework combinations send signals to slots. Other ones have a socket on which you get information about user input.
