Imagine you're the host of a party and you have set up a music playlist using Spotify, iTunes, WMP or similar.
Using the Party Remote app, your guests can up- or downvote tracks while they are playing. If the majority downvotes a track, it will skip automatically.
The app also shows the current track info, including title, artist and cover. The user can save a track to their favorites and later search for it on Spotify, Soundcloud or YouTube.
