How to merge phone music app and Google music.

I can't figure out why Amazon music automatically goes to my music app but Google play music does not. What do I do?

Amazon Music is downloaded as an MP3, whereas Google Play offline tracks are downloaded in an encrypted format specific to Google Play Music. If you want your Google Music files to show up in the stock player, you need to download the music in MP3 format, which can only be done through the Google Play Music webpage (and, obviously, only available for personal and purchased music).
