I've been using play music since it came out and I pay for youtube red or w,e it's currently branded. I can't deny that the reason I chose it is still valid: I can upload my music and stream it. I have obscure stuff that is not in any licensed streaming service and it's nice to be able to pull it up on any computer.

However, there are many severe issues.

* It crashes every single time the app is closed in iOS.

* The ability to edit metadata is missing in iOS.

* iOS integration is missing features that are present in apple music and spotify, such as appearing as a music player in all contexts relevant to the OS.

* Duplicate tracks show up everywhere.

* Playlists often do not update when changes are made to them.

* Playlists sometimes just go missing for a while.

* The web browser interface gets out of sync often.

* It is not clear when tracks are ones in your library or from google's licensed library.

* Uploaded tracks are often deduplicated without warning or notice, resulting in lightly modified tracks and rare releases to be replaced with licensed versions.

* Sometimes I cannot get things to upload without trying a dozen times across multiple days.

This is par for google and it is bar none the the worst software I choose to use.
