I reanalysed the key for all my songs but there is no change in detection accuracy.
How is this still an issue in 2025?
This is just not a serato issue, Many DJ apps have the same issue when analysing music, the best thing for you is to look into "Mixed in Key" software that will fully analyse all your music and give you a much in depth and mainly correct key, as always its not 100%.
or you can always google the key to a song and the correct information will be displayed.
just a tip, you cant rely on any DJ app to correctly give you the BPM, Keys etc. they are all like this.
