im pretty sure the songs are in the key of D but the melodies clash at the drop. Thats why it may sound a little muddy at the end. Thats what I like about it though for some strange reason. Compared to the original tracks my mash is much more intense.
I wouldnt play this at a large festival though. It would probably sound weird. lol
In a studio mix sounds pretty cool though. My reason for sharing.
