I was listening to Morpheus' program on Jordan Page. These are songs written by a guy who is focuses on Liberty.
But I'm aware of one song where none of the "holy words" freedom, rights, liberty, justice, etc. and none of the "evil words" like guv-ah-mint.  And I want to bring this song to your attention with just a few comments about it.
I was inspired to do this by some of the images on-screen during Morpheus' program.  One of the guys has a sign in his lap that reads, "I own  me.  You own you."  Of course, these words convey the Libertarian ideal of "self-ownership". 
The lyrics in the song I have in mind also go to "self-ownership" and even self-mastery.  Slaves "have" a master who owns them.  Free people are their own master, they own themselves.
No one else can do this for you.  No one else can make you (be) your own master.  No one else can be your self-master for you.  Only you can do that for yourself.
The lyrics in this song convey these ideas/ideals poetically.
And the title of the song is:
Unwritten
The performer is Natasha Bedingfield.
Lyrics are displayed on-screen as the song is played here:

Lyrics in popular music comment on all aspects of life, the universe, and everything.  99.99%  of everything ever written or performed ends up on the trash heap of history.  Most likely, so will this song eventually.  But it is one of those songs with lyrics that point to exactly where the rubber meets the road.  And, again, it gets to the heart of libertarian ideals without ever mentioning any of the buzzwords, even once.
Enjoy,
