Maybe eDonkey2000 in combination with eDonkey Bot? Try it out - if you are looking for MP3's don't search for music, search for "any", since many full albums are zipped on the donkey. I haven't tried anything else besides that and the ones you mentioned... And it has the surest downloads ... its "hashing" system guarantees that there would be no file losses... even if your connection is broken, you can resume your downloads where you left....
