After my old PC broke down I was searching for a mastering engineer to give this song a last chance...and I found one!
His name is Mikey Shanley and he did an excellent job!
Here's his soundcloud where you can contact him if you have a similar problem. I recommend him!

Keep in mind this has been completely post-mastered with only the original mp3 as a base.
This version is very close to how I wanted it to be in the first place, so enjoy! :)
Please contact me if you would like to use this in a project. We can discuss the details.
