I'm more than happy with MC.
I originally bought it for its powerful database and metadata editing features. Beyond that, it offers more features than I ever expected to find in this type of software, wanting to just organize and listen to my audio files at the best possible quality. So now, I've started to organize my videos too and am enjoying better playback quality.
I'll buy every upgrade, if only to support the team of developers! Something like $20 every year, where's the problem?
With that constant demand for new features however, I only hope they are not going to overdo it one day, just like Microsoft liked to do (cram enough features in our software, and somebody will buy it).
