Google announced today that its acquiring the streaming-music service Songza for an undisclosed sum. Over the coming months it will be integrating the companys smart playlist creation into Google Play Music and perhaps YouTube. The purchase highlights the increasingly competitive landscape emerging around music, as Apple, Amazon, and Google all seek to differentiate their mobile products by offering top-notch streaming services. Sources familiar with the deal say that the purchase price for Songza, which had raised a total of just $6.7 million to date, was far less than what Apple paid for Beats. Earlier reports on the acquisition from the New York Post said Google was offering around $15 million.
