How to listen to the same song at the same time on 2 different iPhones? My girlfriend stay far way from me, but we have a habit that is listening to music together in the morning. But now we have to do that by playing loud by a Computer so that the quality is so low. I wonder that any IOS app can help us listen to the same song at the same time, i.e. when I press Play button, the song will be played at the same time in my iPhone and her iPhone too.
There are couple of young coders who met at 2013 WWDC after getting a scholarships from Apple who had the same idea you describe. They brought out an app called
Audibly

also connect over a Wi-Fi network.


They still have some bugs to iron out but I have used it and it works well.
