We've seen plenty of ways to turn a Raspberry Pi into a handy music player. Instructables user mkarvonen shows off how to add a touchscreen into the mix so you can also easily control that music right from the Pi.
The crux of mkarvonen's project is Volumio and a touchscreen display from Adafruit. Beyond that, it's just about setting up the software to work properly. There's a 3D printed case here as well, but it's not totally necessary for the project as a whole. You can find the full guide to make this for yourself over on Instructables.
