Access Musics from iPhone on Unity

It’s possible to use the user musics on iPhone, chose it, and play them on Unity ? And from Android ?

I don’t have any idea and checked on internet but I don’t found nothing

If you don’t mind paying for the functionality Prime31 has the MediaPlayer Plugin

MediaPlayer (iPod audio support)$35
One of the most requested game features from users is to be able to play their own music. Add an asset bundle to your project and you are literally one function call away from giving your users what they want. You can even forego the standard Apple iPod UI and play any playlist directly with your own custom UI to fit your game’s style.

Otherwise you may need to brush up on your Objective-C and iOS libraries to write your own plugin
