The song That's All Changed Forever is performed by Embrace .
There's gotta be something
Worth having, worth all this
In my life at last one thing
That I can go along with
I lost half of what I could have been
When I realized you weren't meant for me
And I wonder which good feeling to go with
Till I realized and that's all changed for good forever
There's gotta be someone
I can count on and friend for
In my life at last someone
To make me surrender
'Cause half of what I should have been
Walks away when you walk out on me
And I wonder which good feeling to go with
Till I realized that, that's all changed for good
No more worries or doubts the good will come out
I've changed for good forever
Wait until you see I've changed for good forever
Say you see how much I've changed for good forever
Wait until you see I've changed for good, for good
Just wait until you see
How much a change could make you see
'Cos you don't know better than me
