Gone are the days when sharing music was not only an audible but physical experience. These day, apps have replaced mixtapes and CDs you made for your friends and loved ones. Speakerfy, designed to be used in tandem with Spotify, can be paired between users to stream the same music. For instance, if you and a few buddies end up at the same place, you can link you devices together via magnetic connection and instantly play the same music, cycle between playlists, and collaborate on setting the vibe!
