I used to have a literal wall of CDs. Think I was somewhere around 2500 when I started selling them off. Had a ton of bootlegs, imports and various rare recordings of all my favorite artists.

I kind of miss interacting with the physical product - the art work and reading the liner notes and what have you, but can't imagine going back. Streaming is crap, I still use high bit rate MP3s. Not losing that much in sound quality but it is a whole hell of a lot easier listening to exactly what I want when I want.
