On android it constantly randomly stops, randomly pause and/or closes entirely. If it pause and you press play it closes the app. When a song is over, the next one in a playlist doesn't come on unless you go back into the app. This is really frustrating and irritating when hosting a party or in the shower. I don't know if this is a tatic to get people to pay for monthly or to buy an Apple device (because spotify on Apple has better product use quality). Also, those opportunities you get to watch an add and receive those "ad free music for 30 minutes" most does not in fact lasts 30 minutes. I've done my experiments on that. Maybe this is why people uses Pandora more over this.
