Future Lyricist?

As I've mentioned before, Sam is a total music sponge. She hears a song once or twice, and then it's chorus is permanently embedded in her brain and she can sing all of it within about 10 listens. Even the words she doesn't know the meaning of, she manages to at least mostly pronounce correctly by ear. This is why I have to be so very vigilant about avoiding her overhearing songs with any sort of bad words in them--Thank you All American Rejects for your constant radio play of "Gives You Hell." Sam repeating that song at a family party is so the last thing I need, and I've managed to get recognizing the song and flipping the station down to less than a handful of notes!
Here's a short list of songs we've overheard her singing to herself just in the past couple weeks:
"Man in the Mirror" by Michael Jackson (including the whispered "Make that change!" at the end).
"Firework" by Katy Perry (although I should note that she always says "maybe you're a firework" instead of "baby you're a firework," which I kind of like better. It's like "well, maybe you're a firework, but maybe you're not, I don't know everything about you" and I find that funny because it's so much more cynical.)
"Crazy Train" by Ozzy Osbourne. Yep. I don't know whether to blame Megamind or that Honda commercial with the family in the van, but Sam's shouting of "Going of the rail-els on a crazy train!" is pretty common at our house. Also, rails is a two syllable word. Who knew? "Ai! Ai! Ai!"
"Jar of Hearts" by Christina Perri. She knows every word, and she sings with so much of her soul behind it, that I really can't help but wonder if she does know someone who "is going to catch a cold from the ice inside [his] soul." Hmmm, maybe I should check on that preschool love pentagon of her, Owen, and every other girl again.
"Someone Like You" by Adele. Yep. I better make a call and check in with Miss Carly on the state of Sam's love life!
This is just a few of the songs we hear her singing, but I think my favorites are when she goes rogue and makes up her own ditties. A few nights before Christmas, she was getting her jammies on, and accidentally pulled her undies down with her pants. I told her that her undies needed to stay on and instead of yanking them right back up, she yelled "uh oh," turned around, started dancing, and sang (to the tune of Here Comes Santa Claus)
"Here comes bums, here comes bums, right down your eyeballs lane!"

Hey, I never said she was classy, but she sure is pretty clever.
Who knows, maybe she has a future in song parodies? Move over, Weird Al, a three year old is on your turf!
