Streamed mobile music services and full track downloads are expected to generate robust revenues over the next five years, even in the face of the global economic tsunami, revealed a report from Juniper Research.

The total revenues from these services are estimated to grow from $2.5 billion in 2009 to nearly $5.5 billion in 2013, helped primarily by factors like a greater variety of applications and content, all-inclusive data packages, consumer friendly UIs and an increase in handset storage capacity.

Out of the overall revenue made, the Far East & China region will account for the largest share of mobile music revenues throughout the 2009-2013, with Western Europe trialing behind.

Besides ringback tones is also expected to do well with revenues exceeding those of ringtones by 2010 as service adoption increases outside Asia.

But, to remain competitive, aggregators must expand the depth and breadth of their portfolios beyond ringtones.

However, music services launched using an ad-funded model may confront decline in revenues, as a result of global fall in advertising budgets. Hence, the total spend may fall as low as 50 percent.

In a separate finding by author Dr Windsor Holden, traditional music services like polyphonic ringtones and realtones are set to be phased out by more sophisticated offerings.

“Recent positive developments, such as Apple announcing that iPhone customers can use the 3G network to download full-tracks, will offer a further stimulus to growth,” said Dr. Holden.
