I think my experience is related to this older thread: I set up Google Play Music (free version) on both a laptop (online) and on an Android phone app, both linked to my same Google account. On my laptop, I have a collection of 5500 mp3 songs, which I then uploaded to Google Play Music. I also added several radio stations into my online GPM library. I am now trying to understand the difference between what I see on my phone versus the laptop.
My phone has an SD card, on which I keep the same 5500 mp3’s. I also have a dozen playlists on the SD card. Finally, I also have a folder for downloaded audiobooks and podcasts, which I only have on the phone.
When I open the GPM app on the phone, I expected to just see what I had set up on my laptop – my radio stations plus my uploaded songs. But what I actually see on the phone is that, plus my audiobooks, podcasts, as well as the playlists, from my phone. When I go back to the laptop version I do not see the audiobooks, podcasts and playlists from my phone. So GPM is somehow finding these additional items on my phone and unilaterally adding them in to the GPM app, but only for the phone version. Is this the way it way it works? How does it know to search for these items on my SD card? Since the playlists work on the GPM phone app, are the songs in the library really those on my SD card, or are they the ones from the online library that I uploaded? Thanks!
