Okay, this is a rework of track that’s only few months old. The difference is not so apparent this time, but certainly it sounds better. Cleaner and smooth. Not much more to say here.
I also learned that good mix is not necessarily achieved by making everything loudest and clearly audible – even though it eventually gets there anyway. The good mix is when nothing sounds wrong and gives listener no “WTF” moments. Just as in professional productions you hear on the radio.
