Wasn't there going to be a game that added keyboard?  Or am I remembering it that was the only thing missing?  Hmmm...
Alex, you f'ing crack me up.  I know you don't mean to so that is even more hilarious.  
I read in Oprah mag that one way for people to feel better was to sing, this person recommended that people sing.  Well, I cracked up at that; What about the people who have to 
listen to you sing?  Poor sods.  
Like Lani, I sing all of the time.  Hopefully, she is blessed with a nice voice, as, I am not.  But, I do it anyway.  That Ben Stiller movie, where the girl is singing and dancing in her seat, I was like 'What is wrong with that?'  cause that is me!!!  Especially after a caffiene loaded drink...I'm dancing in my seat,{in the car, for example} doing the cabbage patch, whatever!!  
I would imagine, when the kids get this {as I am sure they will, my Son works at GameStop....} they will not invite me to sing along....  

   But those songs sound like such fun!!
