is it possible to lock an audio file like songs that you transfer with a computer to a phone so that the phone cant transfer it through bluetooth to anybody just like ringtones that comes with a phone cant be sent but only be listened to

Welcome to Android Central! There are file locker apps out there, but I think you'd always have to unlock the file whenever you wanted to listen to it. This is an unusual request--are you concerned that someone might try to steal your music via Bluetooth? Or are you worried that a friend or family member might take your phone and copy music off of it?
