What about FrostWire

What do you guys think about frost wire? For me is faster than limewire and has lots of music.
You can download it here: http://www.frostwire.com/
Remember that after you install it to share all your music :D
Tools>Options>Sharing>Add and add your music folder, the Downloads folder is automatically shared.

I hope you know it cannot "have" more music than limewire since it uses the same gnutella network
