If an app crashes on Android, of course there are no questions asked. We're talking about unresponsive apps, not crashes. And as far as I know, the iPhone only allows "system" apps to be background apps. You can't listen to Spotify while browsing. About the other issue: I think Apple "keeps winning all the time" because of the combination of the consistent experience they deliver bundled with a competitive line of auxiliary services (such as iTunes or the App Store) and very strong branding. There's nothing wrong with that, but I don't think that artificially limiting the choices available to the user is a huge contributing factor.
