LED strip flashing to music

I added green strip to the circuit. For now it flashes to low tones (same as blue strip).

Here is the new schematic:

And another video:

I succesfully added some components, to make LED's shine brighter. I think it could get a bit better by choosing more appropriate resistor and capacitor, but I would need an osciloscope.

As a result, strip draws 350 mA DC from the clean sine wave. Here is the upgraded circuit:

I made some changes to the circuit for the better. If I feed clean sine wave of maximum volume from the computer, 250mA AC flows through LED's. They draw 1,2A of current connected to 12V. If I connect 5V to the base of the TIP102, LED's draw 560mA of DC.

So there is still room for more brightness. This is current circuit:

I am trying to improve the brightness of LED's, so I found out

that adding this piece of circuit:

increases brightness, beacuse LED's dont turn on and off fast with 20Hz (Lowest bass), but stay on more time. This is beacuse capacitor gets charged, and then discharged through resistor slower. (see picture). I didn't succesfuly integrated this in my circuit yet.
