I haven't listened to this in ages.
One thing is for certain, there are massive extra orchestrations. it's noticeable throughout the song. e.g. the 01:40 mark, these melodramatic ones aren't in the original. And many others are also added. Not turned up in volume, but completely new.
I'm wondering if the thing you guys can't put your finger on is the seeming extra punch the drums and bass have. I'm wondering if there is a slight echo effect added to them.
