I lost my Winamp database some time ago (don't ask me how.. it's embarrassing) and have been looking into importing the information from my Last.fm.
There seems to exist a few scripts that do this for iTunes. In theory I can install iTunes (gross), use the script to import there, and then import that data to Winamp in turn.
So I've been fiddling with this awhile now without success and thought I may as well post here.
Has anyone done this successfully? Let me know if so and either way I'll post back with results.
