360 is a known Scam version of LimeWire. They will promise anything to get your money. Known Scam Sites (click on link). Any site that advertises free downloads, millions of songs & videos & games is a scam site. Especially when they claim it is legal. Legality as Birdy suggested depends on your own country's laws. Using the program does not give licence. I can assure you 360 do NOT pay any licencing fees to the music, video or games industries to make it legal.

And remember also, the files you download are shared (uploaded) by people like yourself, the files are not downloaded from a central server. Gnutella network is P2P, sharing between people.

LimeWire Basic is FREE.
