Daisy sings

This is not exactly a new thing, but this afternoon I was noticing the extent of it. When Daisy hears a song she especially likes, she will fill in some of the words either before or after the singer. So for example, when she listens to the first song on her "They Might Be Giants" album, "No!": they say "we just ride giraffes" (she says "raffe" and points to her giraffe); "and wear bicycles for hats" (she says "hat" and points to her head); "To get to Fibber Island you just close your eyes" (she says "eyes" and points to her eyes); "start fibbing in your mind" (she says "mind"); "and see what you can find" (she says "find"). There's a song in which they repeat the word "mop" and Daisy will always start saying, "Mop, mop!" before that part comes up. I think it is pretty neat.
