By Alexei Oreskovic SAN FRANCISCO (Reuters) – Google Inc has acquired streaming music service Songza, the Internet search companys latest move to play a bigger role in the fast-growing online music business. Google said on Tuesday it would explore ways to incorporate aspects of Songza into its existing streaming music service over the coming months. For now the four-year-old Songza service, which creates expert-curated music playlists intended to match users activities and tastes, will remain unchanged for existing users. Google did not provide financial terms of the deal, though a report in the New York Post earlier this month citing unnamed sources said Google had offered to buy the company for $15 million.
