After 40 hours of free mobile music, users will have to put money in Pandora's box17
According to Pandora, the change will affect less than 4% of its subscribers. In fact, the average Pandora listener uses the app for 20 hours a month on all his or her mobile devices. The days of unlimited music had to end since per track royalty rates will rise 9% in 2013 for a total increase of 25% over the last three years. With another 16% increase set to go in place over the next two years, Pandora had to do something to make up for the rise in royalty charges.
Unlimited monthly music is still available for those running the app over desktop and laptop computers. For those who don't want to pay, another option is subscribing to Pandora One, which offers unlimited music and no ads.
