Mobile music and radio company Mspot has teamed up with Island Def Jam Music Group to launch an urban mobile radio service. The service, to be called IDJ Radio, will stream six channels and on-demand content from both Def Jam acts and artists from other labels. Music will focus on contemporary hip-hop, R&B, old school and classic hip-hop and R&B, Reggaeton and Latin hip-hop.

IDJ radio will be available as part of a subscription package from one U.S. operator at launch, to be confirmed at the CTIA trade show in San Francisco on Oct. 23. The launch party will feature performances by Ne-Yo, The-Dream and DJ Green Lantern. The service will be available from more carriers after the launch.

IDJ RADIO is the result of a 2-year development between Island Def Jam Music and mSpot, whose mobile radio services already stream nearly 100 channels of music, news, sports, finance, entertainment, weather and talk radio to mobile phones across North America.
