The rise in musicphones has spurred adoption of mobile music consumption across the United States and Western Europe, reports M:Metrics. The firm reports that sideloading accounts for 83 percent of mobile music usage across France, Germany, Italy, Spain, the United Kingdom and the United States. Among other methods, sharing music outpaces full-track mobile downloading in the majority of these markets. With the exceptions of Spain and the United States, more mobile music consumers listened to music that was shared (for example, between phones via Bluetooth), than was downloaded directly to the phone using a music service. France and the UK posted the highest frequency of this activity, accounting for 12.5 percent of those who listened to mobile music in the month. (PR)
