> I always wondered if we could replicate the physicality of vinyl / CDs, games ROM etc. through memory cards

I kinda like the idea that the music is stored as a raw analog signal pressed or magnetically stirred onto physical media. There's no file format, no codec , no DRM and no CPU involved. It's more of a protest against the digital assault that turned a ritualistic listening experience into a effortless, passive background task.

There's also a big nostalgia factor where a lot of people like me grew up with vinyl, cassettes and CD's when they came out. High school years were rife with tape trading, DiY mixes and kids who made their own music. In HS I knew kids handing out tapes with their fresh new rap or garage grunge band. You won't get that magic back with an SD card in a cardboard facade (or spotify for that matter.)
