I have an Android phone with a 500GB SD card and audio jack. I use an app called PowerAmp. Recently they introduced some optional subscription, but I ignored that, and so far my experience has been fantastic. I've been using that app as my audio player for years already.

I don't get it why people but Samsung S99 Pro Plus Maxi for €9999 when cheap phones for developing markets are objectively better, minus the camera, and cost like €300.
