Here's the text with automatic capitalization without changing the punctuation marks:

Bret's down in his basement
Working hard on his next album
Fed on Dylan and Mötley Crüe
Some mad amalgam
Try and put out of his mind
This will be heard by no one
Some friends, a stranger oceans away
And maybe his mum
Suppose that's some kind of platinum

Bret's down in your basement
Setting up his pedal board
He's been here for hours already
Have you got a spare power cord?
Once he's got started
Well, most have left the party
But he'll still play all night
He does nothing half-heartedly
Don't even sweat about the money

Bret's down in the basement
Of a Thai takeaway place
An old friend of his uncle's
Snagged him this rehearsal space
But his new band members
All of varying skill
Aren't as willing to die on the necessary hills
