Now you can search for available audio online:

Yahoo Inc. on Thursday will begin testing a new search engine feature that will pore through millions of songs offered by popular Internet music services like iTunes, Rhapsody and Napster.

The free service, available at http://audio.search.yahoo.com, boasts an index of more than 50 million audio files, including newscasts, speeches and interviews posted online, as well as the Internet’s deepening pool of “podcasts” - recordings made to be played on a computer or digital device like Apple Computer Inc.’s iPod player. The index identifies the content by reading information - known as “metadata” - embedded in the files.

Other Internet search engines, such as America Online’s Singing Fish and Blinkx, already find audio files, but Yahoo is touting its as the most comprehensive, largely because it has received permission to index downloadable songs offered by virtually all of the Internet’s top music services.
