As a marketing gimmick in 1998, the band Spoon released a track on floppy disk, In the Ground. It was very densely compressed to fit within the 1.4 MB capacity, so you can imagine what it sounded like. I hung onto boxes of old floppy disks for years after they became obsolete, more for posterity than anything else. They’re gone, but this would be something to have for any music collection.
