The music is good, but the mix is VERY LOUD !!!
I knew this was the case right away because I had to jump on the volume knob and lower it significantly to protect my ears. I downloaded your song and uploaded in REAPER and analyzed it with YouLean.
Your song clocks at approx -7 LUFS with a Range of 2.5 and several Max Peaks of 1.6 dB. The wavform is like a sausage -- one big continuous song peaking at 1.6 db.
Does this Police cover song really needs to be competing in the loudness war? If yes, then it is up there in the VERY LOUD department.
