There is no reason to use the new morpheus. Download gnucleus in order to get the exact same program, without the ads.
The thing that makes me mad is the gnutella network used to be great, but now all the people from morpheus who don't share or share one freaking mp3 are clogging up the network, making it slow and unreliable.
I would reccoment Limewire or bearshare, but they both have ads. If you can find limewire 1.7d then download it! No ads, good features, my favorite way of finding things. I stay away from bearshare because the guy who made it is a total person, IMO anyway.
