i don't know whether someone here has mentioned it, but i find that the ending of SLT (smashing guitar) is not coherent with the beginning of Microphone.
the guitarist/bass standing at the left side of the screen doesn't raise his hands in Microphone, while he did in SLT.
and regarding the bleeding contact box, somehow it relates me to sex, u know, when girl experiences it the first time, she will bleed
