I seem to remember Ice-T's Cop Killer igniting a lot of controversy. And have we really forgotten Tipper Gore and her crusade against profanity and sexual explicitness in rap music?

And this song by Public Enemy, for example, was banned by MuchMusic for its anti-semitism. See if you can find the offending reference.
