I felt exactly the same before I joined this forum. Mastering differences are just mastering differences, the mix and the music are the same. As I have said multiple times before, I love Black Sabbath, and if 5th generation cassette tapes were the only way I could listen to their music, I would still do it and love it. Where I notice mastering differences is when I directly and closely compare one mastering of an album to another mastering of the same album. Even then, it takes a little practice to spot the differences in some cases. Some are more obvious though. It is really a question of whether it is something you want to get into or rather not. I am happy I did, because it taught me to draw more attention to sound and details in the music I love. The result is that I am enjoying that music even more than before. However, of course it has its drawbacks. Any minute I spend comparing two or three masterings of the same album is a minute less to spend on something else. This.
