Playbutton asks the question "Why just play a record when you can wear it too?" Not really a pondering that I've given much thought but I can see there being a small niche, hip, market for such things. I can't possibly imagine having an entire music collection chunked out into small wearable pins but I can see it being a fun promotional item to encounter at a festival. It would never replace my current form of musical intake but it would give me pause to listen to the music on it if someone handed me one!
