I understand your point, and (again) thanks for listening.
The amount of effort isn’t that much. The remixing took about 30 minutes. Mastering took about 30 minutes. Remember that everything in my mastering process is plug-in based so I don’t need to wire up hardware compressors or tape machines. In fact, the most effort during mastering for me, assuming the mix is good, is the mid-side EQ. The rest takes about 5 minutes total if that much.
