The new feature appears to be in the early testing stage.
The new feature, which was reported by Music Ally, beatmatches two tracks when shuffle is engaged and crossfade is switched off—this indicates that an algorithm is performing mixes in real time rather than playing back a previously recorded mix. The new behaviour was found in the Drum & Bass Fix playlist on the desktop version of Spotify. It's not yet known if other playlists are part of the test.
A Spotify spokesperson did not offer details when contacted by Music Ally for comment, saying, "We are always testing new products and experiences, but have no further news to share at this time." The streaming giant introduced a similar function, called Party Mode, to its mobile app back in 2015.
The news comes at a time when startups like Pacemaker are courting streaming services with artificial intelligence DJing apps, which automatically beatmatch Spotify playlists into a smooth mix. The thinking is that, if DJ mixes are made directly within a Spotify playlist, then royalties can be properly distributed. Meanwhile, companies like Dubset offer a means to identify and pay rights-holders without replacing human DJs with artificial intelligence.
