While Kanye and Jay-Z were busy polishing their throne, they maybe forgot to clear a sample:

The rappers have used a sample of soul singer Syl Johnson's 'Different Strokes' on their new track 'The Joy', but according to Johnson's publishers, have done so without his permission or any money changing hands.

According to a blog post from publishing group The Numero Group, Johnson, who has previously been sampled by the likes of Michael Jackson and Kid Rock, is well practised at pursuing legal action and is prepared to do so against West and Jay-Z.
