While sites like Youtube and Spotify allow artists to attract enormous amounts of fans, clocking up potential millions of listens, there has been some controversy regarding how much money this actually generates for the artists.

Even 'dead' formats such as vinyl records are potentially more valuable than these new media.
This Guardian article suggests that digital distribution may be yielding surprisingly little money for artists working in the music industry. This would be an excellent example for questions regarding the importance of distribution, marketing, digital media and the internet.
