Clearly, everyone's Grateful Dead zone (or in my case, wing) should be separate and in chronological order.
Everything else needs to be alphabetical to stand any chance of finding things. Classical, funk, punk, comedy, spoken word and compilations also get their own zones. Electronica and jazz may qualify too, in time.
But this is all a bit redundant now that the Sonos multi-room streaming system, plus server and lossless library, are in place.......(not to mention the mammoth task of ripping countless CDs last year in one go). Thoroughly recommended as a way to listen to one's collection a lot more, and more variedly (especially when shuffle mode is invoked).
