Google announced today that it's acquiring the streaming-music service Songza for an undisclosed sum. Over the coming months it will be integrating the company's smart playlist creation into Google Play Music and perhaps YouTube. Songza will remain an active and independent app for the time being. 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.
Here's the Google announcement:
They’ve built a great service which uses contextual expert-curated playlists to give you the right music at the right time. We aren't planning any immediate changes to Songza, so it will continue to work like usual for existing users. Over the coming months, we’ll explore ways to bring what you love about Songza to Google Play Music. We'll also look for opportunities to bring their great work to the music experience on YouTube and other Google products.
Songza also notes that “no immediate changes” are planned, although that usually means that specific features will be integrated into other Google products or that the acquired app (Songza is available on both iOS and Android) will be removed from sale:
Today, we’re thrilled to announce that we’re becoming part of Google. We can’t think of a better company to join in our quest to provide the perfect soundtrack for everything you do.
Songza went through several iterations, and in 2011 it relaunched to focus on curated music recommendations provided by its own team of music experts; in 2012, the company launched a Concierge feature to recommend music based on situations and moods, with filters to refine selections and vote songs. Here's a Billboard article with a review of Concierge from March 2012.
There are many parallels with Beats Music, which seems to confirm that human music curation as an aid to algorithms and traditional search matters.
Music curation is one of themes of 2014 at this point – even Spotify revamped their app homepage to prominently feature curated playlists and recommendations based on mood and time of the day. It'll be interesting to see what Apple and Google will do with their acquisitions.
