I think you should talk to a patent agent and get a method patent on it as fast as you can. Once you have the method patent, then you can worry about how to make it work, and then worry about all the possible legalities. There are phones now that also act as walkie-talkies, and there is a walkie-talkie app that turns a cell phone into a walkie-talkie. I think your music app will probably be similar to that. There will also be music law involved, such as if playing a song on different phones means it is streaming and is a royalty required. Technology moves must faster than law. Get the patent, get the technology, and then deal with the law. Surely this is illegal in some or many ways, but don't let that stop you from developing technology. You can always deal with the legalities on the back end.
