Pitbull is now at the center of lawsuit in which a jury may literally have to play, "Name that Tune."
William Underwood is part owner of a legendary funk track, "Weak at the Knees." Underwood insists Pitbull sampled 'Weak' for his megahit "Timber."
The core of the lawsuit is the guitar riff. Take a listen and judge for yourself.
Pitbull's not being sued ... just his publishing company.
