Spotify works just fine on iOS 7 beta if anyone was worried to test it out.
I just want to let everyone know it works.
Local track syncing works too.
Have fun beta testers! 😃
I've tested Windows 7 & 8 and it allows local file syncing with iOS 7.
I've had no problems with distorted songs, or app crashing.
When I use Spotify, my phone also does not reboot.
Of course, everyone is going to experience different problems, but everything seems to be working for me.
Of course battery life probably isn't the best because iOS 7 is still in beta and there could be background resources that glitch up and drain the battery.
