The Once and Future king

Well I guess
This will be dismissed
As bitterness
And sour grapes

?
Too much time with my own thoughts
It should be my name on their lips
But it's not

And I will wait
For my turn to come round again
And I will wait
However long it takes
However long it takes

See you're gonna
Be the next big thing
All the young girls
You could ever want

I heard your song on the radio
Like a fire-brand on my skin
So the war has begun
A pox on your houses

And I will wait
For my turn to come round again
And I will wait
However long it takes
However long it takes
I say round of applause
I say round of applause
(...he says whatever he wants)

I say round of applause
I say round of applause
(Objection, overruled)

Passive yet aggressive
Drunk on schadenfreude
Success has been cruel to me
My time will come again

And I will wait
For my turn to come round again
And I will wait
