Morpheus is a file sharing application, kinda like Napster. The main differences are that you don't have to go through a "dedicated" server site to get to them. It's more of a peer-to-peer thing....also Morpheus has all kinds of files, not just music. you can get Video clips, Photos, and even entire DVD movies!
You'll need to get the Morpheus program downloaded, and do the installation. Then you can look for the "Blazer" file that was mentioned. It's a cool program and it's worth checking out.
