> I looked pretty hard - I specifically don’t want an android OS called an mp3 player. I want a dedicated media player that has physical button controls (not touch screen), is very snappy, has a good UI, and has a purpose-built OS
There are a lot of DAPs in this style. They're just not popular because the Android-based units are perfectly fine and don't feel like Android phones with an MP3 player app installed. Most buyers don't have arbitrary OS requirements, they just want a device that works well.
