You could look for some used or refurb Samsung Radiant 360 R1's. A quick search shows them available (at least on ebay) for $45-70.
I do not use them for that, but, they supposedly will play mp3's as tracks. They also do speach (which is what I use them for). There is a an app on Hubitat Package Manager for them. I do have to occaisionally clear the queue and refresh them (have a RM rule set up for it).
