Algoriddim has released djay Pro, the first professional version of its djay for the desktop.

djay Pro boasts Spotify integration, giving DJs access to over 20 million tracks instantly. The all-new music library in djay Pro enables DJs to combine their Spotify tracks from the cloud along with their local iTunes tracks into a single library.

The new music library adds features to help DJs work more efficiently, including persistent history and queue, inline search, instant preview, an innovative song recommendation engine powered by The Echo Nest, and track sorting features. djay Pro works on any Mac running OS X 10.9 or later.

It’s available on the Mac App Store for a time-limited, introductory price of US$49.99 (instead of its regular price of $79.99). Go to http://tinyurl.com/ny9hzp9 for more info.
