Yesterday, Lala/MySpace, iLike and Google have officially announced the launch of Google’s music service Onebox — a special kind of Google search results that will let you instantly stream songs directly from Google’s results page by clicking the small play button in your search result. You can either stream the song or buy it. Additionally, Google will also display additional content like tour information and music videos.

The new feature is being powered by two entirely different services: Lala, the innovative music site that lets people buy ‘web songs’ for ten cents, and iLike, the popular streaming music and artist hub that was recently acquired by MySpace. Through this collaboration, MySpace is also leveraging some of the new features it has recently rolled out since the iLike acquisition, including its artist dashboard and extensive library of music videos — you’ll be able to jump to a music video for a song directly from MySpace’s Onebox results. But also Lala will win from this move, as the service’s biggest problem has been establishing traction. This will certainly help with that. Expect the service’s userbase to see a big jump as millions of people on Google are exposed to Lala for the first time.
