is traktor pro and 4 going to able to use spotify premium?
No, not that we know of.
There are at least 2 or 3 active threads discussing just this.
well you should say that they canโt stay behind? But thatโs just my assumption
when!?!?!?
In the last Q&A Traktor dev said they are interested in providing more streaming services. But that does not mean it's coming or what streaming provider they want to integrate.
If you need Spotify now or near future, switch to another software.
Spotify doesnโt allow integration with DJ software for performance use, and DJ apps like Traktor only support streaming services that have official DJ APIs (like SoundCloud Go+ or Beatport Link). So even with a Premium subscription, you wonโt be able to load Spotify tracks into Traktor for mixing.
Spotify changed that recently. You can now use it with for example rekordbox.
Yes - Currently Rekordbox, Serato and Djay Pro. It's planned for VirtualDJ, they're just waiting on approval.
