Well there's still Bearshare. =P
I kinda got tired of Limewire sometime back, last time i used it was back in early 2008, IIRC. If ever i need to get individual song instead of full albums, i turn to Frostwire nowadays.
Does Frostwire use the same P2P network as Limewire or not? Because if it isn't, then no biggie.
