Is something out of key?

[paper gyro]

Hello everyone, I made this(https://soundcloud.com/dj-karlow/maus-maki-bog-i-batinadj-karlow-remix2) remix and someone told me that they can hear something out of key and I'm not quite sure what it is or how to fix it. I have tried some other variations of keys for my instrumentals and baseline as well but nothing seems to sound better or more correct. So if there is anyone with better hearing and knowledge of that, any and all tips are welcome? Also any feedback in general is much appreciated. Thanks in advance.

Hey man! Seriously tight track, cool bouncy feel to it!
It's the vocal thats out of key, but i think there is no way to fix it as it changes key during its duration, goes up and down in a very strange way. I would almost suggest switching the vocal out

Hey man, thank you for replying, glad you like it. Yeah the vocal is kinda strange, I'll look into some other vocals that might go with the mix. Although I almost don't hear that the synth is out of key, it kind feels ok, at least to me. I might just leave it the way it is

Finished the track, didn't bother with the keys and vocal as it sounds good anyway.

fora trakica, posluso sad na mobu samo nemam kod sluske ili monitore sad

cini se solidno producirana al nekako mi se ne poklapa vibe samo uz pjesmu neznam kako da ti opisem

nekako mi je previse lagana traka

nije mi za klub vec za nesto vise chill

al samo rokaj dalje imas potencijala
