How can I sync SMD LED Strips to music?

Plz give me schematic how can i sync 12v SMD LED Strips to music using TIP 31 and PSU as a 12v DC Output.
I get the idea from here

If there is a possible substitute of TIP 31 plz suggest

Thanks a lot guys
is there is way to substitute the TIP 31 with anything else
It really needs to be a "Darlington" transistor, but for the current you're passing, you can make one from two ordinary transistors, if you're really struggling.

See related column on the right as well.
Change the 9V battery to 12V, and put a 100Ohm resistor in series too.
+100, Ohm
