What happens to my Google Play Music library when I unsubscribe? I'm currently shopping for a music streaming service because I'm currently unsatisfied with Spotify, my current service of choice.

Lured in by the three month free trial, I'm enjoying Google Play Music for a series of reasons, but now that I finally moved my library of music from Spotify to GPM, I'm curious about what will happen if I ever decide to unsubscribe.

Will GPM delete all the songs I added? Or, should I ever want to renew my subscription, will I find them all where I "left" them? I know I won't be able to play the songs while on the free level, obviously, but what I'm wondering is if Google will keep all the songs and albums I added, tied to my Google account or, what I'm afraid of, deletes everything forcing me to readd everything once I decide to pay again?
What happens when you cancel your subscription from Google support page says (emphasis added)


When the end of the billing period is over and your subscription is canceled, you won't be able to access music you downloaded to your device, or playlists you created.
If you subscribe again, you'll get access to your radio stations and also the playlists and music you uploaded.


What happens to All Access albums in my library when I unsubscribe from Google All Access? reiterates

If you unsubscribe from Google Play Music All Access and then re-subscribe you will not have the ability to play YouTube videos in the background on Android another setback for some users
