Mp3 players, Do you need one?

I am not a dancer but I love to dance. The husband thinks I am crazy because I could dance and sing for hours and hours. Well, not so much dance but singing is my favorite. I only dance when there is no one else around. Actually, I am not such a good singer either but I love to do it anyway. Of course I am always looking at Mp3 players so that I can store all of my favorite songs. How about you? Do you love to sing and dance too? What is your favorite song?
