OK, I won't.
I'll re-record and see what happens. (But don't hold your breath.)
Nope, it's really a bug, but I can't pin down the
exact specifics other than that pausing a song with a keyboard command sometimes affects playing a new song in the Music interface.
And
here's another bug, albeit an innocuous one, because the red box disappears after a few seconds.
It happens when I QuickLook stuff on my desktop. It happened once in ~/Library/Pictures when I went looking. It seems to affect docs only, not folders.
