Christina Aguilera and the Eagles' Joe Walsh have moved to the DJ side of the radio mixing board with the launch of a.p.e. Radio.

The online broadcast venture is a partnership between Front Line Management and Clear Channel Radio, and formally powers up today (7/31) at Clear Channel's iheartradio.com website with dedicated channels hosted by Aguilera and Walsh, featuring music selected by the artists and DJ banter to provide color to the music mix.

A Weezer channel is scheduled to follow in August, and the company says it plans to roll out additional stations produced by artists ranging from the emerging end of the spectrum to marquee names.

"At their core, artists tell stories," A.P.E. Radio CEO Evan Harrison said in a press release. "A.P.E. Radio will be an additional creative platform to connect with fans and further that storytelling, while ultimately exposing fans to new music."

An early release of Aguilera's channel was followed closely by her tight-knit online community at LiveDaily on Thursday, with an overwhelmingly positive reaction to the production and playlist, as Aguilera pulled together an eclectic mix of material touching The Rolling Stones, Jay-Z, Sia, Nine Inch Nails, D'Angelo, Prince, Gwen Stefani, Metallica, The Beatles and a light sprinkling of her own material.

In a press statement, A.P.E.--which stands for "artist personal experience"--promises the Eagles channel will likewise draw from a wide array of influences and personal favorites, peppered by Walsh's recollections of his experiences on the road and in the studio, from his pre-Eagles days to now.

The platform was engineered to allow the artists and their fans to place player widgets on their own sites, share them across social networks or to listen via mobile devices.

The move comes as traditional FM stations continue to lose listeners due to increased competition from other music sources, including online streaming services, commercial-free satellite radio and digital-music players such as the popular iPod.

(LiveDaily is an operating unit of Ticketmaster Entertainment, which also owns Front Line Management.)
