I've found an app for your exact need. It's called Tags 2 Folders. It's a very simple app and all it does is create folders and put your music in the order you want.
However, two words of caution.
Your tags must be written well if you want it to be in the way you want your folders to look. This app isn't an all-in-one music organizing app thing. It reads metadata and sorts accordingly. As the developer said so himself "garbage in, garbage out"
Apparently there is a problem with the albumartist tag for a few people while using it. It could be due to the version of tags used. All my tags were in ID3v2.3 format, and I found no such issues. Just informing before you take the leap.
I know the guy who asked the question did so 6 years ago, but hey, could help anyone passing by? Hope it helps!
