Thank you for listening Doug, the low mid thing is fixed now I think. I’ll upload an updated version later.
Vocals being too loud? Yes maybe, and if it were my song I’d probably have mixed them a tad lower but since this is Håkons song and he is the star of the show I did it this way 
I hope/think the brightness thing is a mp3 thing, the wave sounds quite pleasant here on my Mordaunt Short speakers/Argon sub woofer
All the best, Kim
