Thanks a lot, I love to hear that this is "prolly one of the best submissions" :D! And I appreciate the feedback too.
The "2nd one" you refer to is likely my '#4 Fragile Prayers', which is actually my song for the next jam (hence the '#4' before it). I apparently accidentally made it visible already, it is now hidden again - I will unhide it when this rating period ends. Please don't consider that song for this jam, I apologize :)
PS: I don't hear any cracking myself, even after extensive listening. I'll keep it in mind if other people have the same feedback.
