I've run into this issue a number of times while producing comedy shows: I want to play intro music for a comedian, but I don't have a staff available to sit there and punch buttons on my iPad. Enter Tango Remote, a handy tool which allows you to remotely control your playlists from iOS to iOS device.
Now I can use my iPhone to not only queue up songs, but change the volume on the fly. It's not only very responsive and robust, it's designed well and easy to use. Tango Remote has saved my bacon a few times, and every time I use it I wonder, "why doesn't Apple build this functionality in?"
In this episode of Origin Stories, we learn about how Tango Remote came to be.
