Google rolling out a search feature that does just that by enabling you to search and more easily discover millions of songs, all via a simple Google web search. If you're searching for music, "time to result" is really "time to music." Now, when you enter a music-related query — like the name of a song, artist or album — your search results will include links to an audio preview of those songs provided by our music search partners MySpace (which just acquired iLike) or Lala. When you click the result you'll be able to listen to an audio preview of the song directly from one of those partners. For example, if I search for [21st century breakdown], the first results provide links to songs from Green Day's new album. MySpace and Lala also provide links to purchase the full song.
