Getting back to the discussion of "most irrelevant pop song," Lori G. submits "MmmBop" by Hanson. (By the way, one of the Hanson kids now has a kid of his own.) MmmBop is definitely in the running if you consider the lyrics:

>>Plant a seed, plant a flower, plant a rose
You can plant any one of those
Keep planting to find out which one grows
It's a secret no one knows
It's a secret no one knows

In an mmm bop they're gone, in an mmm bop they're not there
In an mmm bop they're gone, in an mmm bop they're not there
Until you lose your hair
But you don't care

Mmm bop, ba duba dop
Ba du bop, ba duba dop
Ba du bop, ba duba dop
Ba du
