Sort music by metadata

I thought this would be easier to find but I have tried a number of programs and none seem to be able to do this the way I want.

Basically I want to be able to sort a mass of .mp3s into a specific folder on an external drive, separated and named by metadata. I used foobar2000 on Windows to do this and it was perfect for my needs, the closest I've come on Ubuntu was Picard but, I can't get it to work with music not in the Musicbrainz DB, as I listen to a lot of mixtapes and live cuts so that isn't very helpful.

I want something with an output like "External HDD/artist/album/(tracknumber)title"

(for example :"External HDD/Nas/Illmatic/(01)The Genesis").

Any help would be greatly appreciated.
