> lime wire uses peer to peer technology.
> Its a file sharing software
& yes Its very good for downloading mp3 & songs coz you can get the files by names (unlike torrents which gives the whole album where sometimes you want only 1 song

)
> It doesnt have a feedback system so the files that you see from others can be harmful.
> Best thing is be aware. like a mp3 cant be like 30kB file (in like 99.9999% times ) so if you see files like that suspicious ones where size seems crazy.. Donot get them. & always always scan the downloaded files with an updated AV software before opening them
> If you follow these precautions lime wire can be used for your own good
hope this helps
