Google is chasing mood-based music streaming service Songza, according to reports on Friday. The New York Post says the web giant is looking to boost its music portfolio by adding the online radio service that allows users to pick playlists based on their mood, the time of the week, activities and more. According to the report, Google has offered in the region of $15 million for the six-year-old start up, which has approximately 5.5m active users. Google, which already offers custom radio stations through its Play Music All Access service, may have focused its interest in Songza’s playlist curation and recommendation algorithms.
