The song is about nuclear war. It clearly describes a horrible thing. This is positive? Makes me wonder what you'd call negative.
Musically, I disagree: I think it has more of a NOTB feel than POM, though maybe that fast triple-time section points forward to some POM bits.
Also, searching for this song on my computer revealed that somehow I have not one, not two, but
three different edits of "Total Eclipse of the Heart". The short version, the regular version, and the super-long Jim-Steinman-special "this song is longer than some decades" version. Turn around, bright eyes.
