A website where you can search for and download files - typically music and video clips. A bit like Napster, if you've heard of that. Lots of users of this site swear by it - others visit the likes of Audiogalaxy. You'll need to install a piece of software in order to do this. The site is at:

I have been using MyKazaaGold for years and have never had a problem. You get to download unlimited music from just about any artist under the sun and you never have to pay any fee's per song. They also don't bundle any spyware or other garbage with their software, so it's really safe. Check it out: http://www.MyKazaaGold.com
Kazaa Platinum http://www.kazaa-platinum.com recently came into market. I bought it & I think this was the best choice I ever made.
It gives me specific results for my music & movie downloads, unlike Limewire or any other Kazaa.
It also gives a free anti virus programme , free Ipods/ Mp3 transfer software, free CD burning software free, all in just 29.50 $ one time lifetime fee.
I must say it is a revoultion in music / movies downloads.
