What's wrong with WMP? The 11er has a good number of neat functions. Of course, you need a good virtual sound enhancer running in the background to make it sound the best, but all in all I really like WMP.

What I don't like is Office 2007. I'm fine with a large number of the new features included, but I HATE the fact that the interface was changed 100%ly. Finding anything is a gladiatorial fight now. Even more so, even if you know where it is, it takes much, much longer to edit a bit of text than it did before, i.e. before: all buttons at hand and customisable; now: all buttons hidden behind a squad of other buttons without any possibility to drag and drop them around.

To be fair though, I like the fact that it now suggest all related functions to the object you're editing now.
