How do I allow the mobile user to play own music ingame

i would like to allow the option in my game that is near finish for the user to be able to select his own music and play in the game, is it possible if so how? can he upload his own music? can i use the user media tab?

They would have to upload the music to some website file you have set up and then call it by URL but by the time that is uploaded your users have probably lost interest in playing the game so I would avoid that.

You can give users several music styles to choose from and let them rotate through the choices.
