Before CDs, there were these big black discs called records. Spinning between 33 and 45 times per minute on a turntable, people used to listened to music just like this for nearly a century. Edison, who had trouble hearing, used to bite down hard on the side of his wooden record player (called a phonograph) and “hear” the music as it vibrated his jaw.
Many people today still think that records still sound better than CDs (I think they do), especially if the record is well cared for and their players are tuned just right. Here’s a video on how a record works:

Not really… you might find a kid’s toy one for sale at a garage sale or something. Cheap vinyl records are hard to find, and some people might get upset at deliberately scratching one! 🙂 We have a record shop still here in my town that has one penny records that no one wants – again, perhaps a garage sale? Or “Craig’s list”?
