If it's annoying to black artists and others, it is simply due to their ignorance, which is actually a decision of refusing to view the history of Elvis Presley as it actually occured...
This is the truth, which no one i've heard to this day has had the intelligence enough to break down...
Elvis Presley was called "The King" for more reasons than just his songs. But as far as the inclusion of black songs go in being part of the influence of Elvis Presley being called "The King", the number of black songs he sang (in his unique way) were minimal and were of no influence to Elvis being crowned. What? Tootie Fruitie? Money Honey? Get this straight everyone... it was songs like Heartbreak Hotel, I Want You, I Need You, I Love You, Love Me Tender and Don't Be Cruel (all non-black songs) crooned out with his talented voice and girated to with his sexy style, his handsome looks and his charisma that earned him the title as KING aside from 'HOUND DOG' right? Which was originally Big Mama Thornton's song, right?... WRONG! Big Mama Thornton's Hound Dog was written by Leiber and Stoller! Two white dudes who later re-wrote Hound Dog to suite Elvis Presley.
And so, yes, a white guy comes in, picks up some black songs, sings it his way on the A side of the records, and the black version from the original artists on the flip side (didn't know all this eh?), and he did all this BEFORE he made it to RCA and was shown to the world. After that, he mostly left all that black music behind. The black songs he re-did was barely marketed to the public.
So he's filthy rich not because of black artists, but because of white artists such as Leiber and Stoller, his manager, Colonel Tom Parker, and... HIMSELF!
Hurts... don't it?
