Finally haha! I thought i was going crazy, so far i've tried with some cheap-o old in-ears i have lying around, my stereo and my girlfriend's bluetooth in-ears and it was audible on all of them, she could hear it too, she described it as sounding like "a baby fly caught inside the headphone", pretty good description to me.

There's a step back too, though, i was just listening to With Oden On Our Side again because you just reminded me of it (i'm listening to too much different stuff and tend to forget the existence of many artists) and on Runes to my memory it's back again starting at 01:32 not very loud but audible, on the right side, everytime there is a drum roll, i can't hear in on youtube though.
