Excluding video game OSTs, I would probably say Bad Romance, Camel by Camel, Chop Suey, or Somebody's Watching Me. (I can't pick one, I like them all.)
Out of the four songs I just listed, which one do you like the most?
3 cats! We used to have some dogs, but sadly, it was just too much for us. They both went to great homes, though! One went to my grandmother who needed a companion while the other went to one of my best friends!
