Floppy Drive Music
YouTube user MrSolidSnake745 released a couple of videos playing music on floppy drives. The videos below are Derezzed from Daft Punk and the Battlefield 1942 Theme, but you can find a lot more on his channel. You can do it yourself with the software of Sammy1Am, which can be found at Github.
