Is Janis Better Mama Music than Joan?

Miss B's next library pick was Janis Joplin's "Pearl." After DJ B was done checking out Joan Jett, she asked for "more mamas" and pointed to the Joplin CD. We put it in the boombox and, like Joan Jett, it elicited smiles and dancing.

The next day, when given a choice among her new picks, she again pointed at Janis Joplin. When we played it, DJ B started to dance with her glittery toy princess cell phone case. She put on a hat, then put her headphones on over the hat. After realizing that didn't work that well, she took off the headphones and hat, then put the headphones back on her head and attempted to put the hat on over the headphones. Unsuccessful, she began to throw the hat in the air, yelling "throw!", "hat throw," and finally, "I want milk!"
