Using a file system as a metadata storage system is pretty dumb - especially when music files have ID3 tags built into their formats. There are tools that will help you fill out the metadata in the tags based on your file system layout. Once you do that you can use the tags to slice/dice. Smart Playlists are very powerful.
Or you can use one of the many other apps others linked to if you really want to stick to the whole filesystem thing.
I quickly got away from trying to organize stuff in the file system when I got my Personal Jukebox 100 (PJB100) - literally the first hard drive based MP3 player out there in the mid 90's. It heavily relied on MP3 tags so I developed tag discipline early on - and never looked back. Tags are WAY more flexible than folder structures. I couldn't care less how files are stored in the file system.
This conversation always amuses me - we don't complain the computer tracks all the parts of our files in a directory while we have no control over the layout of the files on disk - mainly because that's a level of minutiae better left to automation. For me it's a similar things with my music files. As long as my tag information is accurate (and since it's the first thing I do when I add something to my collection, it is) I can manage my music collection however I want irrespective of where the file is.
