She is super inspirational. Her song firework really helped me through tough times when my ipod died. Her chorus for firework is so magical when she rhymes boom boom boom with moon moon moon, i die of happiness. Also you you you is rhymed with moon moon moon. Lastly, she tops it off with rhyming ah ah ah with ah ah ah.
"boom boom boom, even brighter then the moon moon moon! It's always been inside of you you you, you'll make 'em go ah ah ah when you shoot across the skah skah skah *cue Katy Perry shooting across sky going "weeee!"* you're gonna leave 'em goin' ah ah ah"
