I've heard about efforts to standardize the podcast format, and that might work as a way to propagate music as well. The problem is then the software that will aggregate and play those files. Will it run on your phone and do you have the appropriate audio jacks or bluetooth capability so that you can listen to the music?
At least in Japan I see a lot of proprietary efforts to tackle this issue. There's very little interoperability unfortunately.
