How can we learn idioms in an easy way?

Idioms song:

You got the best of both worlds
A penny for your thoughts
The ball is in your court

Curiosity killed the cat
At the drop of the hat
Take with a grain of salt

Not playing with a full of deck
Wouldn't be caught dead
Hit the nail on the head
Best thing since sliced bread

It's a golden opportunity
And actions speak louder than words.


Rhythm: Hannah Montanas song
