There are many upsides to this app. For example, the mixes are awesome and pick pretty cool songs, but the playlist and song library functionality is absolute garbage. When I press shuffle in my library, I don't want to hear the first 10 songs I recently added, sometimes repeated twice in a row. Also, if I "unlike" a song, that means I don't like it! So remove it from my song list! I'm sure google will sort this out, but until they do 2 stars is my best. I wouldn't recommend over Spotify.
