Mastering is crucial to give your song the necessary loudness and balance. I always do my best during mastering to get that extra something out of your track.

Of course, I always try my best to fulfill your wishes during mixing/mastering. However, please remember that my personal perception always plays a role in the process. It's best to listen to my references before purchasing to better gauge if you like my mixing/mastering style :)

It's best to sort all tracks in the project by their function, e.g., Hook Mains, Part Mains, Doubles, Adlibs, etc., and name them accordingly so I know what's what. This greatly simplifies my work and also ensures that I understand your vision! Furthermore, you should not record your tracks too loudly to prevent clipping.
