What would people give, for a cassette tape?

A story

On the 28th of October, 2016 A.D., I bought a cassette tape at Lithe House.

On the evening of the same day, as I distractedly looked at the cassette tape, on the bus home, wondering if the cassette deck at my house was still functional, I looked up to see a stranger smiling at me.

He and I exchanged a few glances. Later, he invited me to his house.

Another evening, at his house, he passed a few more cassette tapes to me.

Will someone value the cassette tapes more than I do?

Out of curiosity, I am experimenting with a swap to see what value cassette tapes have in a world where technology changes. There will be no money involved. What would people offer in exchange for these tapes?

I didn't want to swap, until the cassette tapes started to gather dust at my father's house. Will there be a better use for them?

This effort will last for forty-five days, beginning from 9th November, 2016 A.D.

Details of the cassette tapes are available at a shop at Carousell
