Cool project! What I miss most about switching from CDs to digital music/streaming is the CD art/booklets. Yeah, I know, that itself was a far cry from the art on vinyl record sleeves (mostly because of size constraints), but still, if I built one of these, I would probably make the cover images bigger - or even provide a sleeve in which to insert a CD booklet (however I guess that would be difficult with a Rolodex?).
