Google Inc. is buying startup Songza Media Inc., bolstering its music services as it tries to draw users away from rival Apple Inc.

Google has no immediate plans to change the song service, which selects tunes for listeners based on a person's activities and the time of day, the Web-search company said on its website. Terms of the deal weren't disclosed. Google said it will consider how Songza might be integrated into its Google Play music services and other properties, including video website YouTube.

"They've built a great service which uses contextual expert-curated playlists to give you the right music at the right time," Google said.
