Songs:

Linking Park – In the end

I tried so hard

And got so far

But in the end

It doesn’t even matter

I had to fall

To lose it all

But in the end

It doesn’t even matter

Queen – The Loser in the End

Mama’s gotta problem

She don’t know what to say

Her little baby boy just left home today

She’s got to be the loser in the end

She’s got to be the loser in the end

Misuse her and you’ll lose her as a friend

She’s ma on whom you can always depend
