Filing your music alphabetically - C/D?

Old system, until this afternoon:
- Collections for each decade, with each decade alphabetized.

New system:
1. All my 5-star records are in a separate section on the top shelf, alphabetized.
2. Jazz gets its own section. Though I may backtrack on this decision during the next re-org.
3. Everything else alphabetized (I collated all the decades in a massive merge sort operation)

Seems reasonable, my mate has always advocated a separate section for the best stuff, the theory being it will encourage more listening of favorites over endless crate digging.

sorted by whether or not the pile has been knocked flying recently.
With most recent purchases on top or possibly most recently played.
Always make sure you have more than one pile of cds around you and that most of them are obscured either by having other stuff piled on top of them or by the rest of the pile. So when you go to find something you are bound to find something else entirely.
Keeps your listening fresh or not as the case may be.

Idgi - if you organize by rating, don't you have to remember the rating of every record you own in order to find anything quickly?

For records: Alphabetical by size (12", 10", 7"), and then one square dedicated to new purchases, old favorites, and passing fancies. That square gets wheedled back down to a handful every few weeks as it slowly fills up and spills over into the turntable area. Another two long shelves are "to be sold" LPs/12"s and 7"s, which are every so often sold and every so often re-evaluated and put back in the main collection. My wife's LPs are another shelf, and another section is absolute dreck I was given by friends who know I like records and which I should throw out but...

CDs: In boxes in the garage attic. Not convenient, but no real CD player anymore and no room in the house. Hoping to get a dedicated CD player again when we do some remodeling and regain some space, and then these will come back in.

Cassettes: So few left, but these are in two small boxes nears the LPs. Getting my old Aiwa refurbished so i can play these properly again, as I've purchased two cassettes so far this year (Poison Ruïn and Angel Bat Dawid) so maybe more to come.

Yes I do, but it gives me a chance to reevaluate each time I play an album.

Also, I have my entire collection rated in discogs, so I can always fall back on that.
