This is sorta a talking blues kinda thing, from The Arrogant Worms

BIRTHDAY SONG

Once a year we celebrate with stupid hats and plastic plates
The fact that you were able to make another trip around the sun
The whole clan gathers round, gifts and laughter do abound
And we let out a joyful sound and sing that stupid song

HAPPY BIRTHDAY Now you're one year older
HAPPY BIRTHDAY Your life still isn't over
HAPPY BIRTHDAY You did not accomplish much
But you didn't die this year so I guess that's good enough

Lets drink to your failing health, hope you don't remind yourself
Your chance of finding fame and wealth decrease with every year
Does it feel like you are doing laps, eating food and taking naps
And hoping that someday perhaps your life will hold some cheer

HAPPY BIRTHDAY What have you done that matters
HAPPY BIRTHDAY You're starting to get fatter
HAPPY BIRTHDAY It's downhill from now on
Try not to remind yourself your best years are all gone

If cryogenics were all free then you could live like Tim Leary
Your head, for all eternity inside a block of ice
But instead your time is set this is the only life you get
And though it hasn't ended yet sometimes you wish it might

HAPPY BIRTHDAY You wish you had more money
HAPPY BIRTHDAY Your life's so sad it's funny
HAPPY BIRTHDAY How much more can you take
But your friends are hungry so just cut the stupid cake
