Tangerine! lets you easily create playlists of upbeat music, or playlists for relaxing.
It works by analyzing the BPM1 and the beat intensity of your music. Spend your time listening to music, not making playlists.
To start, fire up Tangerine! and add playlists from iTunes, or drag in a group of tracks to work with.
