i personally don't think it does but then again i'm not a producer or the artist that spend tons of money in the studio the real question is there is no way to stop it fact is some ppl would want to buy the orginals and others won't for some gys they buy just to share it on net so in my view no it don't it gives the consumer a chance to listen to the music and let them make up their minds if they want to purchase it so many of us has bought a album and the thing was no good at all except for the single that we saw on tv so no is my answer
