Mobile-music ventures involving Christine Aguilera, Lily Allen, Ludacris, Sugababes and Dirty Pretty Things are up for trophies at this year's Meffys, the international mobile entertainment annual awards ceremony.

Sony Ericsson's 2006 pan-European initiative starring Christina Aguilera is a contender for the inaugural artist campaign category, which is intended to distinguish the difference between mobile-music services and mobile marketing involving an artist.

Also shortlisted is handset maker Nokia, which engineered a "mobflash" artist campaign at London's Waterloo train station last year for its new N91 multimedia handset and linked it to "Waterloo to Anywhere," the debut album from Dirty Pretty Things (Mercury Records).

Other nominees for the artist campaign award are Endemol Digital Media for the "Get Close to...Sugababes" project, Parlophone/New Visions' "Lily Allen Mobile Site" and Mercury Music Group for "Ludacris Three Front Room."

Finalists in the music service award category are: London-based Omnifone, operator the new international online music service MusicStation; California-based Mercora and its streamed-music service Mercora M; Hingi, Israeli operator of music-recognition service Hear It 'N' Get It; U.S.-based Groove Mobile, which powers U.K. downloadable mobile-music service 3 Music Store; and French wireless carrier Orange, which operates the Orange Music Store with Musiwave.

Now in its fourth year and organized by the Mobile Entertainment Forum (MEF), the Meffys aims to recognize and highlight achievements in the mobile-entertainment business, which MEF says will generate $38 billion by 2011.

The winners will be announced at this year's Mobile Entertainment Market (MEM) confab, which takes place on June 5-6 at Monte Carlo's Fairmount Hotel where key speakers include Barney Wragg, EMI Music's head of digital worldwide; Ole Obermann, Sony BMG Music Entertainment's VP, global digital business; and Gideon Bierer, senior VP, digital media at MTV Networks International.

It is the first time in MEM's seven-year history that the event has been held outside London.
