I love Kazaa, just because I can grab whatever media I want, when I want to! If I hear a song that I like on the radio or somewhere else, I merely hop on Kazaa, and a few minutes later, my download is done and my music is ready to listen to!
One con to Kazaa is that it contains spyware, which allows advertisers to spy on what youre doing on your computer. To avoid this, try KazaaLite or K++ (Which I prefer.) You can fink K++ at https://geocities.com/rndkpp/
Although I know Kazaa is rampant piracy, I dont plan on justifying my actions. Piracy is the way of the internet at the moment. When the tide shifts, so will I.
The interface on Kazaa is very straightforward and easy-to-use. You can click on various buttons to bring yourself to places where you can search, monitor your traffic, listen to your music, and more!
Although Kazaa has a messaging function, I dont use it much. People on Kazaa arent to amiable and they often arent at their keyboard. Kazaas more of a faceless, nameless place.
For review purposes, I just downloaded a 3 MB file in under 3 minutes. Now, I do have broadband, but its still very fast for whatever connection speed you have.
Kazaa is great just to grab a few songs or videos quickly.
