i wonder how much you tube has been a factor in less cd sales, illegal downloads are already old news and have been replaced by the free jukebox that is youtube.
if big record labels think tackling illegal downloads is still a main issue, they are still behind the times.
go to any student party and you will see youtube on, with people taking turns in picking a tune, its pretty social, and free. there are even programs to copy the music strait off youtube, and even ones to mix 2 youtunes together.
the choice is far greater than free illegal downloads. try and find a torrent of a recently released drum and bass tune and it is difficult, and a lot of effort to find what you want, but everything is on youtube, most of them posted by the artist/label themselves (not including main stream music). youtube is also great for finding new songs, by looking at random peoples playlists ect.
