I always had the idea of making the playlist creation process for DJ's more fun and modular by having groups of tracks (TrackMatches) that serve as components for final set playlists or templates. This enforces reusability of tracks and also makes the process of preparing a set for the next gig much faster. Of course you first need to build up your TrackMatch collection, ideally when mixing at home or with friends. When you discover 2 or more tracks that blend really well together, simply open the app and create a TrackMatch out of these tracks. You can then drag and drop the TrackMatch into as many playlists as you like. The app is in a "MVP" state and still misses a lot of features, like having other sign up options (not only spotify), or having TrackMatch recommendations, etc. I'm very much open for any feedback and feature requests or even collaborations :)
