7. F**k the Police by NWA
Considered the founding fathers of gangsta rap, the group NWA hit the headlines in the late 80s when their song F**k Tha Police shook up the music industry and gave birth to a new genre of rap that was full of anger and hatred toward authority figures.
Once again, by todays standard this is nothing out of the ordinary, but at the time, NWA were considered public enemy number one!
