The title is less nonsense than it first appears. Cassettes are riding the coattails of vinyl getting popular again as collectibles. Lots of medium sized bands added vinyl to their merch stands to great success with their fans but the total manufacturing capacity of vinyl is small and everyone was suddenly competing for it. Not to mention when Taylor Swift drops an album and buys it all. Enter cassettes, another piece of physical media that's easier for artists to get their hands on and has similar collectible properties.

Neither vinyl nor cassettes are going to make a dent in terms of music distribution, but that's because they compete in the same market as band t shirts.
