re: Need a good non-phone music player that works with Amazon or Google

Someone else might chime in with a different solution, but as far as I know there is no music player that will do what you need.

Maybe there is an iPod you could use, and get Spotify or apple music

However, an iPod is going to have the same functionality as a phone without the sim so you would be better off with just an old Android phone paired to Google play music
