Just heard this song called "No Handlebars". This song sounds like criticism of the government. It's pretty cool. Check it out: https://www.youtube.com/watch?v=NvNvkXD_gs0
Ok so the group that sings that song is called Flobots. I just bought their album on itunes. I'm not a rap fan generally, but this group is great. They're really political and kind of refreshing. Check them out if you get a chance.
