One of the partners in my studio and I often discuss things that you did in one day that made you grow as much as your normally do in two months. These leap points are what we are looking for in mixing since the skill takes so much time to master. One of those leap points is when I discovered the wonder of sitting in front of my speakers during downtime (importing files, transfers, naming tracks etc.) and listening to as diverse songs as possible back to back in order to learn the little nuances of all of my monitors. Hearing the difference in bass between Fela to Burzum, Acceptance to The Clash is one of those things that really gets your head around how songs are shaped. You start to see similarities you never heard before hearing two tracks back to back and begin to understand details you never noticed. This simple tip made me learn more in a weekend then I normally learn in months of working. I am sure it can help you too.
