I spent so many hours finding a user on Napster (or Soulseek) and looking through the albums they had in their collection. Maybe it was because there was a higher barrier to entry for an album getting into a person's collection back then -- they either had to rip it from CD or download it on relatively slow connections, and hard drive space wasn't what it is now of course. It's not anything like favoriting a song or album on a platform like Spotify, even if you could browse their saved albums.

I'd love to have discovery require a little bit of work again, there was a lot of fun and playfulness in digging.
