I'm surprised they weren't doing this all along. Who wants to store 200,000 versions of "Some Nights" instead of 1 (or even 5 or 10). Even if the client was md5ing all the music and only keeping unique ones...it'd allow at least everybody who downloads from any given service or anything distributed digitally to be consolidated big time.

um...you can. i think 5 separate downloads (although it is drm-free, so you could download once and share amongst your devices if you felt like it).
most inconvenient thing i saw was the one file (download) at a time limitation without installing the client. probably a browser issue, though, more than a service problem.
