Led Zeppelin
Led Zep is arguably one of the greatest rock bands of all time. Poignant lyrics and killer guitar riffs made the band great. While it may be true that they 'stole' some melodies from lesser known blues performers, but all music must come from some where. People take inspiration from great music, so these lesser known artists should be flattered. Led Zep paved the way for all that was to come after, and erased all that went before. A truly genius band and contrary to what other definitions might state, all ages still enjoy their music. I've been a fan since I was 13 and stumbled upon a poster at a car bootsale that depicted them.  Townies and similar illiterate scum may not appreciate them, but what do you expecy from a life form stupider than ameobes. At least ameobes are interesting.
Absolutely no example needed.
