Music is always a pleasant commodity at a social gathering, and such are the trends of modern technology, that most people have their entire library (or at least, an assortment of favorites) in their pocket at all times. Unfortunately, the rigmarole of chopping and changing between devices to source different artists and songs is an altogether less enjoyable experience, and can make the process rather tiresome at times. Thankfully though, one developer has come through with a solution to this common occurrence, having created an app for iOS which allows all on the same Wi-Fi to curate a playlist mixing songs from different devices. It's called GrouPlay, and although it doesn't solve the issue of cringe worthy dance moves, will allow the party to continue with less interruption.
