Thank you so much man, great feedback, as I am a music producer and I have good ears I checked 1:37 again, well its exactly on tune, its the dark chord I chose for that part :) , if you listen to music in this genre you will hear this kind of changes in chords. I can tell you what happened in there with chords : it went from F# Major to G Major, which it made that kind of sound which we both wanted it to sound that way, as this is not a pop song :) and if you want to understand it better it was like this = Chorus chords were : E - F# - C#m - G#m and then in the second part which you didnt expected it to sound that way it was : E - F# - G .

its a pleasure! thanks for listening and thanks for the kind words :d
