Alphabetizing Subfolders?

[agolden]

So, weird thing happened when I reinstalled 4.7 on my new OS install: while the sidebar folders are correct, when you choose one of them, all the subfolders in them are semi-disorganized alphabetically. There are some listed A-Z, followed by some more listed A-Z with year, followed by MORE A-Z with no other identifier. As an example, one listing might look like this:

ACDC
Air
[...]
ZZ Top
Aerosmith 1999
Bad Company 2000
[...]
Yngwie Malmsteen 1985
Brian Setzer Orchestra
Boyz II Men
[...]
Wham!

I hope the above example makes sense! Anyone else have this problem (or, better yet, know how to fix it?) Thanks!
