It's not weird, but, I basically sing + rap to songs on my ipod while dancing (usually while cleaning) around my place. I sing & rap in the car when I'm alone as well. Quite common.
I strut while I listen to music. Doesn't really matter if the music isn't even up beat. I'll work an emotional strut if that's what the song calls for.
Is it weird if i bop to music like someone who is having epilepsy or being possessed in bed? I did that alone when i listened to MATHANGI (which is always available in Itunes by M.I.A)
