From ReadWriteWeb:
"In 2011, we collectively listened to 64,876,491,602 songs on the Internet. Whether it was on YouTube, SoundCloud, Rdio or MySpace, the citizens of the Web listened to quite a lot of music last year. Bands and musicians made over 3 billion new fans, who viewed artist profiles over 16 billion times. These are just a few data points recently released by Next Big Sound, a startup that tracks the popularity of music and individual artists across a range of digital music providers and social services."
"What's interesting, though, is how the Web is paving the way for unsigned, independent artists to reach levels of popularity that rival major label acts. This is especially true on SoundCloud, where unsigned artists flock to upload their recordings. But even across the larger Web, three unsigned artists broke into Next Big Sound's "Social 50" list, which chronicles, the 50 biggest artists across all of the social and music sites that they track."
