Internet giant Google is buying a startup called Songza Media Inc., which is developing a music service that selects tunes for the user based on his activity and time of day, Bloomberg reported .

Google said it has no plans to make changes to the service, but will consider integrating Songza into its services, including Google Play and YouTube.

Terms of the deal were not disclosed. A source for The New York Times said that the deal amount exceeded $39 million. In early June, the tabloid The New York Post wrote, citing a source, that Google offered $15 million for Songza.

Google is strengthening its music services in an attempt to win back some users from Apple, Amazon and Microsoft, Bloomberg notes. These companies are trying to transform their music services amid growing user interest in streaming music through Pandora and Spotify rather than downloading albums.

In May, Amazon introduced its own streaming music service, Prime Music. Apple that same month announced its $3 billion acquisition of headphone maker Beats Electronics, which owns the Beats streaming music service.

Songza was founded in 2007 in New York. The company has raised $6.7 million in funding from investors including Amazon, Lerer Ventures and Metamorphic Ventures. In 2010, the Songza team sold its music service Amie Street to Amazon. Currently, the Songza service has about 5.5 million active users.
