It looks like Spotify is testing a new auto-mix feature.

First spotted by Music Ally in the desktop version of the Drum & Bass Fix playlist, songs are seamlessly mixed by selecting the shuffle function. This means the playlist isn't playing a pre-recorded mix, instead shuffling through songs and beat matching in real-time. It works pretty damn well, too. 

This isn't the first time Spotify has ttrialled mixing technology, having launched the Party mode for its mobile app in 2015. But as Music Ally reports, this is something new.

“We are always testing new products and experiences, but have no further news to share at this time,” a Spotify spokesperson said.

With recent technological gains made by Pacemaker, a startup that automatically turns Spotify playlists into seamless mixes, there is some speculation as to whether or not Spotify is testing Pacemaker for possible long-term integration. 

But the billion-dollar streaming giant could very well be testing its own software, bringing the automation of music selection further into our reality.
