Songza was my favorite music app, had IMO by far the best playlists.
Google has now integrated Songza into Google Music.
I'm now a Google Music subscriber, very good move by Google. I said forever MS or Google needed to buy out Songza and integrate it into their app, given both of their radio/playlist features sucked.
Currently a Groove Music subscriber as well. Will likely be dropping it soon. Went with the family plan on Play Music allowing for 6 users for less than the price of 2. Cheaper than individual subscriptions for me and my wife on Groove.
I've already figured out how to stream Play Music to my Xbox via DLNA from my phone. Works perfect. Sounds good.
Google kept Songza's free features but stepped up the advertising. Only took 1 full day of listening for me to pay.
