C64 disks with custom loaders (read: games disks) were so fascinating to me as a kid because the sounds of the 1541 drive would change as soon as that fastloader code activated. Lots of game disks had their own unique loading sound signature. I would love to see a comparison of 80s floppy disk drives. Lots of genius designs within... except the 1541's terrible bug which was never fixed due to backwards compatibility.
