Your earworm is ...

[icehog3]

I know that it's evil
I know that it got to be
No I ain't doin' much
Doin' nothing means a lot to me
Living on a shoe-string
A fifty cent millionaire
Open to charity
Rock'n'roll wellfare

Sittin' in a Cadillac
Listenin' to the radio
Suzy baby get on in
Tells me where she wanna go
I'm livin' in a nightmare
She's looking like a wet dream
I've got myself a Cadillac
But I can't afford the gasoline

I got holes in my shoes
And I'm way over due
Down payment blues
