Wouldn’t it be cool if when you disconnected your headphones from your iphone and plugged it into an aux jack from your car, the music just continued playing?
I face this issue each time I’m coming from the gym, in the zone listening to a song, then I get into my car and have to change the connections. I absolutely HATE having to bring up the music app and hit play to keep going. It would be amazing if for 5/10 seconds after you disconnect the headphone jack, the iphone just auto resumes playing whatever was playing before, if you plug it into something else. The interesting thing is that if you connect to a bluetooth device it already does this by default (continues playing from where you left off), this would just be a more explicit extension of that user experience pattern.
