General :: Automation - Good Console-based Program To Automatically Manage Music Collection?

I like the convenience of having a music player that manages the placement of my music files based on the tags of the files, sorting into a root music folder with Artist/Album/01 - Track Title.mp3 sort of hierarchy. Previously, I was using Banshee for this feature, as even most of the other gui music players don't have this library management feature. Now, I've been trying to use console-based applications, and I have been using mpd + ncmpcpp fairly successfully. When I download new music, it is downloaded to a specific folder, and that's not part of my music collection. My previous workflow would be to open a gui filemanager at the downloaded folder, and drag and drop those songs onto banshee, which would then make a copy of those files in my library hierarchy. Currently, I'm doing the same thing, using Banshee only as a sort of import program, then closing it and updating my mpd database, and there we go.

If at all possible, I'd like to automate this to something where I can define a watch folder, and when some magical program sees new music in said watch folder, it identifies the correct place for the files to be copied into my heirarchy, renaming folders and files to the correct format. I know I've written a lot describing, but I don't actually think this too uncommon a task, and I'm wondering if anyone has a solution for my problem.
