More Robert Plant

I'm still convinced that Apple engineers are toying with me. I'm currently at work, listening to tunages on my iPod. Five songs into a 1470-song playlist (this is the playlist that excludes songs played in the past four months), I hear a Led Zeppelin song from the early 70s (Robert Plant, lead singer). Song seven is from the Honeydrippers from the 80s (Robert Plant, lead singer). I know that statistically it's possible this was a truly random occurrance but I'd rather believe that Apple engineers toyed with the iPod random function. I'm gonna keep an eye on them because it's the kind of thing I'd do and I know that I can't be trusted.
