i have watches videos of people using the moto x to play their music using the google music app. with the 'Google Now' feature, it often times not locate the songs i have in my library, but instead link me to site like youtube to play them. Also, with the songs that do work, it does not auto play them, instead, the the keyboard pops up and the song is searched, but i have to tap on it to play. What's going on?
