MixShape lets you control your mood music http://bit.ly/YKNtNK
The “digital age” has allowed music lovers to play music using a shuffle button, and sometimes, you end up with a “mood killer” or a song that disrupts the flow of the mood. MixShape hopes to bring back the glory days of the cassette tape and your ability to queue songs in a fluid manner. You can enter your Spotify playlists, choose an appropriate occasion (party, work, exercise, romance), and MixShape will analyze the contents of your playlist by rearranging it to create the best flow. MixShape will even remove any songs that don’t really fit well with the theme.
