Well, they shut down two music services. The first was Songza, which they bought. They then took everything Songza had- namely their awesome mood-based, artisanally curated playlists- and put it into Google Play Music. Then they seemingly let go of everyone who maintained the playlists and never updated them again? Those playlists on Songza were _excellent_ and the Snoop Dog collabs were just delightful.

Not sure how Google internally makes decision but I imagine it works entirely quarter by quarter trying to measure individual Impact with no overarching vision or direction.
