Android MP3 Player App that Reads from micro USB port

[jjtauber2]

Want to use old Android phones as MP3 players. Have large library on USB stick with micro interface, so it will fit into the input port on Android phones. Need Android MP3 player app that will know how to read the MP3 library that is on the USB stick and allow playing by artist, album, music category, favorites, shuffle, etc., including full shuffle of complete library. Thoughts?
