Plonkety Piano is Here, The Notes Swing, Sway and Leer

Did you get a downvote?
It's all in the melody, the rhythm and the mood.

It could be up, or it could be down. Can you sway this tune?
Classical, it's Bach. Smooth it's Myleene Klass, Country it's Carrie Underwood.

Upvotes may come, and they may go. The wind and the rain will blow.
I will strike day by day, to those who feel that they should pay.
