fo.write('''All the times that you rain on my parade
And all the clubs you get in using my name
You think you broke my heart
Ohhh girl for goodness sake
You think I'm crying
Oh my ohhh, well I ain't!
And I didn't wanna write a song
'Cause I didn't want anyone thinking I still care, I don't
But, you still hit my phone up
And baby I be moving on
And I think you should be somethin' I don't wanna hold back
Maybe you should know that
My mama don't like you and she like's everyone''')
