Suggestion
 

First, LimeWire is, IMHO, the best file sharing utility out there. Still room for improvement though, right? My suggestion is that you allow multiple "Shared" folders, and be able to specify default download folders for different file formats, i.e... .mp3 defaults to the Shared-MP3 folder, .avi-.mpg-etc... default to the Shared-Video folder, etc... It would be great! It's just something I wish I could do.

Why don't you create a directory on your hd with your favourite file manager and move the mp3s there?

And don't forget to share that folder with limewire afterwards...
