She has the same facial expression all women give me when I ask them if they would like to come over to my place and play "sink the submarine."

Maybe if you had offered your battleship she may have been more interested.

I can learn from you. Thanks for the strategy!

BSR - BattleShip Ron

I got most of these; If you're playing along at home:
Attempt 1: Clair de Lune (Claude Debussy)
Attempt 2: ??
Attempt 3: Moonlight Sonata 3rd Movement (Beethoven)
Attempt 4: Harry Potter theme (John Williams)
Attempt 5: Pokemon theme (John Siegler)
Attempt 6: Flight of the Bumblebee (Nikolai Rimsky-Korsakov)
Attempt 7: ??
Attempt 8: Russian National Anthem (Alexander Alexandrov)
Attempt 9: Get Along Gang theme (don't know who wrote this)
Attempt 10: Blue (Eiffel 65)
Attempt 11: Thomas the Tank Engine theme (Mike O'Donnell/Junior Campbell)
Attempt 12: Funeral March (Chopin) I'd be surprised/alarmed if she smiled at this (!)
Attempt 13: Jaws theme (Williams)
Attempt 14: Halloween theme (John Carpenter) this too (!)
And the winner..well, you know, a chick song from a chick movie, no wonder she smiles...

I think #2 is "Eminem - Love The Way You Lie ft. Rihanna"
I think #7 is from Daft Punk?

OK I had to do some investigating cause it was killing me.
#2 is River Flows in You (Yiruma), never heard of him
#7 is Shooting Stars (Bag Raiders), never heard of them either.

COMPLETE!

Correction of title: What INSTRUMENT makes a girl smile...

TL:DR - forget the time and expense of learning piano, get a slide whistle instead!
