In his most-recent blog post, Pandora founder Tim Westergren revealed the breadth and depth of Pandora listeners' streaming tastes (and the service's offerings) as reflected in some broad-based 2012 listening stats.
According to his stats, Pandora listners heard more than a million different songs by over 100,000 different artists in 2012. Of these artists, 10% were streamed to more than a quarter-million unique listeners. This totalled over 13 billion hours of music in 2012.
"The Pandora audience is large enough now to begin making a real difference in the lives of thousands of working artists," wrote Westergren.
