I am starting to dislike YouTube Music for cramming in music I don't like no matter how many times I use the thumbs down. I have already tried Spotify and Apple Music and didn't like either. I do buy records from Bandcamp but a streaming service is necessary as well. Should I try Deezer? Pandora not available here. Or even Amazon Music?
Pixels unfortunately don't have a MicroSD slot, but it's easy to play back local audio files on their internal storage. Download Musicolet or any other music player app for music playback, and FX file manager for robust file management (although you can get by with the stock Google Files)
