Check out WinMx from winmx.com if you are a windows user. it's the best I think, the software forms it's own network of other winmx users, not too many just yet, BUT even while your participating in that small non-centralized mx network it will allow you to connect to as many or just search from and download from all the other napster
and napster clone servers SIMULTANEOUSLY(Opennap there's thousands of them) I was searching for live shows of [b]String Cheese Incident[/b] the other night, they are not very well known at all (they kick major ass if your into Jam-Grass) I connected to around 10 opennap servers plus we had the mx network, I got over 700 hits. even napster at its biggest didn't have that much 'Cheese. And thats my Cheese-Barometer method of guaging how much stuff is out there. and it does any type of file, videos sounds appz anything, and you can browse another users entire listing, cool.
