Peter has an old Walkman, which is about 40 years old. But when he presses play, the cassette plays for one note and stops. Leo has a hunch that the motor in the walkman is probably worn out. If it can play other cassettes, that would point to the cassette that's gone bad. It could be fixed, but Leo suggests digitizing his entire cassette collection because the older they get, the more likely they will start peeling off the oxide coating and he'll lose his music. He should get a Crosley Cassette player and digitize them. He can convert them to MP3 and get an mp3 player or a smartphone to play his music.
