Comment 1 for bug 1504639

Hi Nicolas! Thanks for taking the time to file this issue and help make Ubuntu and the Music App better! The idea of adding support for streaming services, including Google Play Music, has been discussed every so often amongst the team. One problem with integrating Google Play Music, is that there is no publicly supported API(s)--only unofficial ones. This would mean that the support for Google Music could break at any time and we'd have to wait for a fix. There are other issues design issues surrounding integrating streaming services in general in the app.

I think the best idea, for now, would be for a 3rd party to create a Google Music downloader that could save the user's library to the device for the Music app to use.

I hope this helps!
