I personally am an avid Gnucleus user at the moment and the one feature that I love is the ability to search within your search results... you just type in a band name and then search within your results for each song... 1 query for like 14 songs... it's wonderful and a lot quicker than researching the network again... it probably saves bandwidth in the end (more initial query hits but after 14x searches you have fewer redundant replies)...
