I vary the records I have that are like that. For example, sometimes "ESPM the reunion: Live at Akhbar Hall" is snuggling between "Blowin' the blues away" and "The Charles Earland organ summit" (which is another moveable one with McGriff, JH Smith and Dr Lonnie); sometimes it's cuching up beside Mel Sparks' "I'm a gittar player"; other times it's dividing its affections between Teddy Edwards and Houston Person's "Horn to horn" and "Close encounters" (if those CDs aren't on duty in the Teddy Edwards section) or if they are, between "Christmas with Houston Person" and "Personified"; and sometimes it's elbowing its way between Idris Muhammad's "My turn" and "Right now".
This might seem daft but it's actually moderately helpful. I only do it for Soul Jazz, not for any of the other kinds of music I collect. And it's because I have about 36 feet of Soul Jazz CDs. I keep some spaces in the shelves so I'm not faced with having to shuffle all 36 feet along when I buy a Cannonball Adderley CD. But those spaces aren't necessarily in the right places to accomodate new CDs easily. Moving one or two from here to there gets around that problem. Of course, from time to time I DO need to shuffle the whole lot along, to create more extra spaces. But it doesn't have to happen nearly as often.
The general rule is, chronological recording dates by alphabetical artists by type of music. Frankly, when I want to listen to Mbalax, I don't want to wade through tons of other stuff to find something I fancy playing. Ditto Blues, Gospel, Sermons, R&B, Swing, Hip Hop etc etc.
