I have a prime 4 and I went through a drum and bass (174bpm) playlist and a happy hardcore playlist (165bpm) and did all the best gridding but when I play the playlist on the Denon prime 4 it’s playing them at double the speed, too fast.
How can I fix this?

Do you need to analyse them using the correct BPM range? Check the settings for analysing them, you want one of the higher options.

I don’t see how the beat grid (regardless of being wrong or right) would affect the playback speed.
Is there something you didn’t mention (e.g. you’re syncing it with another track)?

I’ve had a similar problem with beatgrid info suddenly changing and tracks needing re-analyzing, might be that: [Speed of random tracks wrong all of a sudden](https://community.enginedj.com/t/speed-of-random-tracks-wrong-all-of-a-sudden/52060)
