Google has reportedly struck a licensing deal with the 4 major record labels (Warner Music Group, EMI, Sony, and Universal), which will allow them to permit Google-users to buy and listen to music from the Google search results page. The deal is said to be a maneuver by Google to stay relevant and competitive with new search engines- namely Microsoft's Bing.
According to The Wall Street Journal, while Google is the clear leader in the search engine market (they had 64.9% of the online queries in the U.S.); Microsoft's Bing is slowly increasing in popularity. Bing had 9.4% of the queries in the United States in September 2009. This is a 1.4% increase from their May 2009 stats.
