And if you go to myspace, last.fm, or a bunch of other sites and search, you'll see that many new artists post their music online to freely download. And these artists are hardly major labels.
The fracking point is that it is the artist's (the copyright holders') right to post previews, free tracks, or streaming audio, and their right alone to make that decision as to what how and where their property gets posted or copied.
To argue that stealing someone's work -- downloading it without the copyright holder's consent -- is legitimate because you then spent some money on a show or on a CD, is just a lame excuse for wanting something for nothing.
Something for nothing - that IS the bottom line. The whole bunch of you who make all of those convoluted rationalizations just so you can enjoy listing to someone's music without paying for it - you make me ill.
