Where do you go if you want to buy your fave band's latest single?The shops? Or to your computer?
Well for those of you who like to download music there's some good news.
Even the head of America's recording industry, Cary Sherman, thinks that illegal music download sites are here to stay.
Even though there are lots of court battles to try and shut them down, he says that free music will always be available from somewhere on the net.
Worse album sales
Illegal downloading is bad news for the music industry because they believe that if people can download music for free then you might not buy the album.
Companies hope that they will be able to control the amount of illegal sites and encourage people to start to pay to download music from proper sites.
