[Narrator] Mister Know-It-All.

I can't stand inane toddler music,

but am I impairing my two year old's cognitive development

by spinning Zeppelin instead of the Wiggles?

As long as you keep your kid from seeing

the Houses of the Holy cover art,

her brain will be just fine.

There's exactly zero evidence that one kind of music

helps cognitive development more than any other.

Plus, the supposed benefits of music come from

learning to play an instrument, not just kicking back

and admiring John Bonham's drum solo in Moby Dick.

I certainly agree that Do The Monkey by The Wiggles

belongs right next to the Barney and Elmo theme songs

on Volume One of Beelzebub's Greatest Hits,

but don't forget the first tenet of parenthood:

It's not about you.

Toddler tunes sell because their simple lyrics

and catchy melodies make rugrats boogie and sing,

and spark a lifelong appreciation for music.

So if your tyke digs kiddie pap,

more than Physical Graffiti, suck it up.

A little Wiggles now may pain your ears,

but it could mean a whole lot of love

for the better stuff down the line.
