Why do blacks say that whites stole their music?

Firstly, I know that some white singers have stolen from blacks, like Elvis, but what about the opposite? I never hear any blacks complaining about how much blacks have stolen from whites. Here are some of a few examples. If you want even more, I'll oblige.I don't understand why you say this, but forget to mention the mive amount of songs that blacks have sung, that were written by whites. Most of Whitney Houston's song were written by whites, pretty much all of Dionne Warwicks songs were written by Burt Bacharach and Hal David, and Aretha Franklin had a lot of her songs written by whites. Examples are I Will Always Love You and Step By Step, I'll Never Love This Way Again and You Make Me Feel Like A Natural Woman.
