Remember cassette tapes? They were a great way to listen to your favorite music and a cheap one at that. Cassette tapes were all the rage in the eighties and nineties (even though they were invented in Belgium in 1963). Cassettes would later fall to the wizards at Apple, Google, and Sony, but cassette tapes had one heck of a heyday.
On this list, you’ll not only find great blast-from-the-past ‘80s and ‘90s music, you’ll also discover some of the most expensive cassette tapes on the resale, vintage-lovers market. Perhaps you have some of these tapes; if so, you could be sitting on a gold mine.
