I attended the Music Apps Hack Weekend, February 24 – 26, 2012, conducted by Spotify. My team created a prototype dating app called Music Match-Maker. It utilizes the modern concept of ambient social networking.
This dating app will broadcast your location and what song you’re playing through Spotify to other users around you. You can see on a map other users near you, what they’re listening to, and how similar your music tastes are using Last.fm’s Tasteometer API. You can use this app to find people with similar interests, new friends, and maybe something more. Eventually, you will be able to use Foursquare and Facebook to check–in to places, have a simple messaging system for correspondence, and be able to recommend music to others, either automatically based on match percentage, or out of your own inspiration.
