The mobile music market in Western Europe will continue to boom within next three year, as the overall mobile music spending has grown more than double from US$636 million in 2006 to $1.7 billion this year, and is expected to achieve $3.25 billion in 2011, research firm eMarketer announced.

In 2006, more than 80 percent of the spending came from ringtones and ringback tones, which accounted for $515 million. However, they are losing ground with time. In 2011, they are expected to reach $1.63 billion, but only represent 50 percent of overall spending.

On the other hand, full-track downloads mastertones, which totaled merely $121 million in 2006, are getting much more popular these years. They will reach $1.63 billion in 2011, accounting for half of the mobile music spending in that year.

eMarketer also stated that there is a growing trend of ad-supported mobile music. In 2006, it only accounted for $5 million, but is expected to grow over 50 times to $260 million in 2011.
