This is my most-used playlist, and more than any view. Reason is, unless I am actively exploring for new music, I don't want to be bothered searching through 80% of my library. At the same time, I want to load my favorite (5,000) tracks into playing now in some new (non-random) order that strikes me at that particular moment. Top hits allows me to do that quickly and powerfully.
I also appreciate being able to EDIT the parameters on the fly. Sometimes I want to see every song I've ever played (num plays > 0), sometimes I just want to see all the 5's.
