It plays songs. If you pay $$, sometimes play queue actually matches songs being played &sometimes even in order. No multi-select, must add songs to lists 1-by-1. You think you're choosing order, but usually doesn't actually play in that order, its just re-ordering the list you see as you're adding/listening. Starts current song over every time you add one. If you tap song title instead of 3dots next to it, clears entire list & replaces it w/that song. No way to undo or go back, it's just gone.
