Ghostly Discovery is the first free iPhone application that provides users with playlists depending on their moods. It uses mood-based tagging to create playlists from Ghostly International and Spectral Sound.

Ghostly Discovery offers different color hues that resemble different types of moods. The user simply has to select a color and a random playlist will be generated to coincide with that mood. You can also choose the pace of music with the faster/slower slider.
