How old a version of LW are you refering to? I guess it depends on platform. I know for LW 4.8.1 on a mac it listed them alphabetically.

But personally I don't take all that much notice of the saved files folder. I use iTunes which will arrange my music into artist>album. 1. Albumwrap/iTunes , 2. iTunes shared library That gives me easy access to whatever music when i share those folders. Since iTunes arranges the songs like this according to their id3 tag. But you need to get them into iTunes 1st. Sorry if this is a little off-topic.
