A new study from Forrester Research shows that while listening to music on mobile devices has doubled in the past year in the U.S., the country still lags far behind the U.K. and China. The study found that ten percent of mobile phone users in the U.S. use their device for listening to music, whereas only five percent did a year ago. However, 27 percent of British mobile phone users and 70 percent of those in "metropolitan China" use their mobile devices for music listening, according to PaidContent's summary of Forrester's study.

Data from Forrester's study showed that those surveyed in other countries are less likely to use MP3-only players and also have a wider range of music available from their mobile carriers. However, buying songs via a mobile device is a different story. Just three percent of Europeans who listen to music on their mobile device also have purchased music over their phone, and 60 percent of U.S. phone owners surveyed said they were not interested in buying music on their phone.

The executive summary of Forrester's study says that "Uptake of music on phones in the U.S. has been lackluster so far. Part of the reason is that mobile and music providers have focused on their business models first and the user experience second. Europe and Asia have fared better in terms of user adoption, but direct revenues from mobile music remain lean. "
