Its funny if I have voice command open and I say "Play artist Outkast" it'll load up a list of all the outkast albums. If I try Play Artist Outkast Album Idlewind it'll just resume playing whatever the last song I had playing in the music player. Oh it also has a popup that ask if I want to use Iheartradio, Pandora, or the factory music player (theres an icon at the bottom to make default). If I had google music installed I would think it would make the list as well.
It kinda sorta works sometimes, but not exactly a great experience. Theres also a pretty good chance I'm doing something wrong
