On the topic of playback rate/pitch fuckery, Janet Jackson's "Rhythm Nation" was sped up ever so slightly after recording (as was sometimes done at the time to make the music sound more "exciting" or "intense"), and that's one of the hypotheses for why playing it interferes with laptop hard drives: the dominant E frequency/pitch got shifted up to somewhere slightly sharp of E (but not quite E#), which just so happens to be closer to some drives' resonant frequency.
