Hopeless Happy Song

What is it? Sounds like a hit
Keeps buzzing round my head
Brings a swing to your hips, a smile to your lips
But it makes me see red
It's good when you shop, makes your heart-rate drop
Worries drift away
You don't have to listen to the silence
That's what you really hate
There's a little melody ringing in my ears
Sounds so peaceful and so sweets, soothes away my fears
There's a hopeless happy song burrowing in my brain
It tears my heart to pieces, it's driving me insane
Can you boogie to the revolution?
Can you shimmy to the holocaust?
Can you tap your toes to your troubles and woes?
Can you join in with the words?
It's unconditional surrender
It's the bland leading the blind
It helps you find your way through the dreary day
But it's making me lose my mind
There's a little melody ringing in my ears
Sounds so peaceful and so sweets, soothes away my fears
There's a hopeless happy song burrowing in my brain
It tears my heart to pieces, it's driving me insane
