After purchasing music from google play, is there a way to download the physical file directly to your phone from the play app? I'm not interested in streaming from the cloud or caching. Specifically, I bought an mp3 of a ringtone and need the actual file so I can set it as a ringtone (google play music app doesn't have the "set as" option and the standard music player doesn't see google play songs). I know you can use a computer or even the phone browser to download it via the play website, but there should be a way to do this within the app right?
