FxPlaylister lets you discover music in your library or in other libraries that contains various sound effects and themes from a set of thousands in a training database. Results include metadata and can be queued, copied, played or purchased across a variety of APIs, music sources & products. Users will be able to create tags from their own music sources or use existing tags from the cloud-database of built-in samples and tags. DJs, TV and movie producers, advertisers and discographers can do research and create content for their own projects using FxPlaylister. It goes beyond Pandora in that many specific similarity relationships are supported as opposed to a broad, single measure.
