From the developer:
Kado offers a convenient way to find new tracks for your DJ sets. You can drop a track into the application and Kado will use data from over 500,000 DJ sets to show you similar tracks. You can quickly preview a track in Kado to see if it fits the style you are looking for.
Kado doesn't just give you track recommendations. If you like a track you can click on it to see all the remixes and similar tracks.
You may want to check out more Mac applications, such as Speak or SH-201 Librarian, which might be similar to Kado.
