Kendrick lamar thanks jay z for clearing the heart pt 5 sample without charging him watch

I think there may be some misinformation here!

While Kendrick Lamar and Jay-Z are both respected figures in the hip-hop world, there is no evidence to suggest that Jay-Z cleared a sample for Kendrick Lamar without charging him.

In fact, Kendrick Lamar has spoken publicly about the challenges he faced in clearing samples for his music, including the high costs associated with obtaining clearance from original artists or their estates.

It's possible that you may be thinking of a different artist or situation. Could you provide more context or clarify what you're referring to?

(Also, just to clarify, "Watch" is not a specific song or album by Kendrick Lamar or Jay-Z, so I'm assuming you meant to ask about a different song or project.)
