> I guess buying the vinyl is like buying a shirt or a poster now?

Yeah, in some way that's true. In the house music scene almost every producer also sells vinyls of their best songs, sometimes "collectors editions", and also DJs obviously sometimes pride themselves on only playing vinyl. For the artists I really do enjoy, I tend to buy their songs + with the vinyl, as a way to support them, but I indeed have no way of actually playing them, and haven't had for more than a decade.

So here I sit with 20+ vinyl records, most of them unopened, and no record player. But I don't mind, I just want to give money to the artists that provide me joy.

I still have my old BluRay collection which I build up from the mid 2000. This already was the replacement of the DVDs I had before. They still sit in the shelve because I don’t know what else to do with the space. Same goes for books etc. I mean I really like the covers etc and the fact one has a physical token. But I simply have too much of it in my house already. And replacing the stuff yet again feels useless. I also like the feeling that if I wanted I could simply let go. Before someone asks: The unit the BluRays are located is a TV unit. And getting rid of them would mean I have an empty shelve. They also cover the cable / power cord mess behind it a bit. So removing is actually not a solution. I would either need a replacement to put there as a cover or get rid of the TV unit shelve thing :). Typical 1st world problem that is.

Yeah, I've done this. I've bought records for years but only bought a record player recently. I would want to buy something at the merch table for a small band I like. They don't always have a shirt in my size but they always have records. Oftentimes the records went on loan to friends, which was a nice way of gently spreading my taste.

Yeah, I also buy digital for this reason.

some do it as speculative collectible too

Albums are art that can be displayed and one of the most accessible forms of real-art-connected-to-the-artist.
