FrostWire
The best P2P sharing client I’ve used till date. It uses the Gnutella network, and has been written in Java, and thus is a bit heavy on resources. But the search, result filtering, sorting, and music playing features make it really cool. It has all the features of the very popular LimeWire, but the icing on the cake is that unlike LimeWire, FrostWire is free and open source. Available for Linux, Windows and Mac OS X.
