I agree. I'd like to see a lot more "Mixing.." tutorials. And I'm not sure it needs to be limited to one per genre. Different people mix differently and seeing how other people (especially people with lots of experience), approach tracks.
I watched the Mixing Pop even though I don't have Pro Tools. Once you know your way around one platform pretty well, the approaches translate pretty easily.
For me, these have been some of the most interesting and valuable tutorials here. I've gained insight and fresh ideas (and, incidentally, been turned on to some great plugins in the process). And I'd love to see more of these types of tutorials.
