Sure, physical media for the average consumer is no longer a thing. We sold vinyl records, and that is still a desirable thing for the niche markets. So, maybe just think of it from a slightly different angle/perspective. Make it a collector's item. Collectors want physical product to own/possess/show off. There's still a market for physical forms of musical recordings. If this is really a niche product, then cater to the niche market. The niche market knows/accepts it is niche and there's a bit of a premium mark up that can be taken advantage of here. Surely, you're not the only person looking for this type of sound. Capitalize on that like we did. Do it as a side hustle. Reach out to labels that own the rights to the track you like. Put together a compilation. Produce the physical product. If you don't do it, who will? Granted, it's way more work than just pirating a copy from someone else.
