I remember listening to music on cassette tapes. After awhile, they would wear out, but could be fixed using plastic adhesive tape, though you'd always hear a fade when the mend came around. I also remember making mix tapes and "dubbing" was a big deal when I was a kid. Before then, you would just place two tape recorders side by side to copy music; one would play while one would record. Ah the good old days!
