Easy:  I know the popular stuff!

"Your lipstick stains on the front lobe of my left side brains.  I knew I wouldn't forget you and so I went and I let you... blow my mind." 

Medium:  I know music! 

"Maybe if I act like that,(woo) that guy will call me back.  Porno-paparazzi girls, I don't wanna be a stupid girl.  Maybe if I act like that, flipping my blonde hair back (yeah).  Push up my bra like that (uh-huh), I don't wanna be a stupid girl." 

Hard:  I am a Music Guru!

"Desperado.  Why don't you come to your senses?  Come down from your fences, open the gate.  It may be rainin', but there's a rainbow above you.  You better let somebody love you.  (let sombody love you).  You better let somebody love you...ohhh..hooo before it's too..oooo.. late."

 

Extremely Hard:  Music is my Religion!  (You can't stump me chump!)

"Here's to the liars and the cheaters and the cold mistreaters to the mama's boys who can't make a stand.  Here's to the superficial players.  The I love you too-soon sayers.  If you hear me girls raise your hand.  Let's have a toast.  Here's to findin' a good man."
