Social-networking site MySpace is launching a music video service that will pop into millions of profiles at rival Facebook as well.

Starting Wednesday, music videos that MySpace has licensed for its site will run as well on the iLike music recommendation application, which the News Corp. unit acquired this month for $20 million.

Music videos have always been a part of MySpace. With the new service, MySpace-branded ones will also be playable inside iLike applications embedded on competing social networking sites such as Facebook, Bebo, Orkut and hi5. They will replace videos that iLike used to get from Google Inc.'s YouTube.

Advertising embedded in the videos will benefit the MySpace Music venture, which is jointly owned by MySpace and the major recording companies.
