The activity around mobile music apps is at an all-time high, but few seem to know what strategies are working, which ones are profitable, and where the fast-changing market will go next. The aim of Billboard’s upcoming Mobile Entertainment Live: The Music App Summit is to bring together the brightest minds in the business to examine the market’s past, present and future.

To that effort, the morning keynote program will kickoff with Janus Friis, the serial entrepreneur who co-founded Kazaa, Skype, Joost and the newly-crowned music startup of the year Rdio. Friis doesn’t make a lot of public appearances, so this is one of the rare occasions to hear his philosophy on technology innovation, startup investment, and the delicate balance required between developers and content provides.

Christy Wyatt, VP of software applications and ecosystem for Motorola Mobile Devices joins him on the program to talk about the hottest mobile application platform in the market right now—Android. Motorola has turned around a struggling phone business on the strength of this operating system, with Wyatt in charge of its growing developer program (a role she previously held at both Apple and Palm).

Matt Murphy is the partner at legendary venture capital firm Kleiner Perkins Caufield & Beyers overseeing the $200 million iFund, which invests in up-and-coming mobile apps such as the Shazam music ID service. Murphy, who has been on the cutting edge of mobile app development ever since Apple launched the App Store, will lay out how the market has evolved in the past two years and where the smart money is going in the year ahead.

Finally, Ge Wang is the co-founder and creative visionary behind music app pioneer Smule, developers of such hit apps as “I Am T-Pain,” and “Glee.” Using a mix of informative slides, real-life case studies and entertainment demonstrations of his company’s apps, Wang will take attendees behind the scenes of how a blockbuster app is conceived, developed and sold.

Additional keynotes will be announced soon. Mobile Entertainment Live: The Music App Summit takes place Oct. 5 at the Moscone Center in San Francisco. It is an official pre-conference of CTIA Wireless Enterprise & Applications.
