How does this circuit look,do you think it will work? The LED's in this picture are Blue 5mm LED, 6000mcd, with a 3.3Voltage drop and a max continuous current of 30mA.. max peak current of 70mA.

My hope is that the LED's are powered by the 12v, but only turn on and is bright when the music plays hence the and gate. Your thoughts suggestions and comments please? :X
