I recently came across 2 songs "Letter From the Governement" and "Learn Truth" by hip-hop artist Talib Kweli.
I am not sure if Talib accepts voluntarism, or where exactly he stands philosophically, but I was very pleased to hear a rather main-stream artist express such definace toward the State.

"Learn Truth": http://youtu.be/o_t2JRnZdGA
Lauryn Hill also brings truth to bear on the statism in "The Mistery of Iniquity"
I was going to select a favorite sequence, but there are too many to cite.

In my experience, songs that present truth and raise skepticism toward state power are very rare and deserve to be shared.
Enjoy
In Liberty,
