But the one from Spotify still says G (DJ Pro analyzed it; DJ Pro has played it, too).
The one from iTunes still says A (DJ Pro analyzed it; DJ Pro has played it, too).
The 2 files are identical. They’ve both been analyzed by DJ Pro. Yet, the issue remains.
It does not appear that DJ Pro’s analysis changes the key provided by Spotify. I have never seen it change, personally. But, BPM can (and often does) change after DJ Pro’s analysis.
Again, this issue is not limited to the above-mentioned track: the majority of tracks I have from iTunes and analyzed by DJ Pro show a different key than identical tracks from Spotify and analyzed by DJ Pro.
Thank you for your time. Cheers.
