Startup Idea : Spotify mets Facetime

You are in a train,walking down the road,whatever. The only friends you have is your earphones and your music playing and you are really vibing that song at the moment,with just a tap you can see which friends are online on spotify and start facetiming them while the song is playing on their phone on the exact same minute as your song on your phone so basically you are listening to the same thing but without actually being together. P.S THIS is just an idea the feasibility of it is a whole other story (would require partnership with spotify etc.) but I just wanted to see if anyone thinks this idea is cool so let me know :)
