Plays cds and mp3s just fine. The "hold" button is vital once play has started -- the buttons on the face-plate will activate if you are carrying it around, like in your pocket -- so play is easily interrupted, or the screen info will change in unexpected ways. If you don't turn it all the way off with two clicks of the "stop" button, the play will continue and the batteries will drain, resulting in a very unstable performance that will start play and stop after a few minutes -- annoying til you figure it out. I use this to play old time radio catalog radio shows, and the manual fails to explain that holding down the "next program" button will give you a fast-forward function. It's bare-bones, rattles a bit, but it plays good and the price is right.
