I can redownload the files I uploaded as FLAC, but they download as lossy files. I don't think I can get at the originals.

Plus my playlists are full of tracks that were available in Google's subscription service that I didn't upload.

My account isn't ready to transfer to yt music yet, but I'm already dreading it. Yt music streams at a lower bitrate, and you cannot download the highest quality (but you can stream it??)

Also, the thumbs up/thumbs down buttons are switched in the yt music ui vs GPM. Bad ux across different products... Par for Google, I guess.
