The window of opportunity to catch wireless users interested in mobile music services may be closing soon, according to In-Stat analyst David Chamberlain: Those users are ready to buy new handsets and they're willing to pay extra for handsets that play music, and carriers without music services could end up missing a lucrative market, reports Mediapost (via MediaBuyerPlanner).

According to a recent In-Stat report, mobile music in the form of downloadable music files or broadcast digital radio is generating more interest among U.S. mobile customers than even gaming, which is currently providing some of the greatest mobile data revenue.

But widespread adoption of music applications could be slowed until issues such as pricing, revenue sharing, and digital rights management can be solved.
