As an artist,you put out your work for the public to consume and use in any manner they see fit. The work stands on its own as soon as its lefts the artists' hands, with the creator no longer holding ownership. Pete needs to understand that as a public good, TROY will be manipulated, discussed, or used in a manner he does not see fit. Lupe though, needs to respect the responsibility that comes with reworking what is one of the most important songs in hiphop. I'm not against using the sample, but the work has stand up to, or improve upon the source material.
