As seen through the eyes of a thrift crawler...
I could be wrong, but a cassette revival (to whatever extent) seems like a natural progression in the order of things.
As the demand for used vinyl has gone up, the availability of desirable titles in decent condition has decreased either by virtue of collections going to dealers instead of thrifts and so on (although, locally, the dealers are having a hard time finding collections to buy to keep their bins stocked) or, loved ones are keeping the collection for themselves, not releasing into the wild. And of course, if they do make it out of captivity, they are snagged almost instantly, nothing is sitting there collecting dust, thats for sure.
So, that situation, in my eyes, forms somewhat of a vacuum which is at least partially being filled by the next best plentiful analog media, cassettes. At $.50 apiece or so its easy to take the gamble and even if 2 out of 3 are bad, the one good one makes things worthwhile.
Other way I've seen it is at least I have the title on tape..and that can hold me until I stumble across the same on vinyl (which has actually worked out a few times).
Did I just jump on this bandwagon because I felt pressured? No, never gave up on cassettes and have managed to acquire some decent decks through the years which have kept me in the game, without them I could very well have given up.
Oh...btw, anyone else noticed there has been more traffic on the site concerning 8 track? Or is that my imagination?
