Last night on my way back home I noticed something very strange ! As I was stopping due to a red signal, I had noticed that the lights of the Car's stereo are blinking !! as I was playing a CD. when I was moving, the blinking stops. yet this happened for several times, until I reached my house and looked again at my stereo but it was not blinking !!! but I had the feeling that the blinks were related to the beats of the song, or shall I say related to the drum beats or something !! is it normal guys ?!! or something is wrong !!
