Yahoo! has launched the beta version of their audio search. The new search engine has apparently catalogued audio files from around the internet -- music and voice, including those on sale at online music stores. In one fell swoop, Yahoo! has moved to position itself as the gateway to online music stores, the same way other search engines, especially Google, has positioned themselves as the gateway to great information storehouse of the internet. Interestingly enough, the results for music searches provides a list of competing online music stores, one of which is Yahoo!'s Music Unlimited store. It opens the possibility that Yahoo! could use it search function to undercut prices offered by competing stores, by automatically adjusting prices in the search results. Whoever said that internet search was a public service?
