Internet: File-sharing helps raise the popularity of established groups and singers

[bbc] File-sharing sites help make popular acts more popular, finds a study.

The research, by industry body PRS for Music, showed the most pirated pop songs tend to be those at the top of the music charts.

There was little evidence that file-sharing sites helped unsigned and new bands find an audience, it found.

It suggests file-sharing sites are becoming an alternative broadcast network comparable to radio stations as a way of hearing music.
