Luciano Pavarotti didn't write songs or play guitar either. He got paid for singing. You can't market what isn't good. The people bought the music.
Elvis sold a lot of records, millions of people bought them. In his time when you bought records you played them. No video, no Ipod, people played them to hear him sing. His career was also interrupted by military service.
There are the Beatles, I did buy their music.
Then there is Elvis.
He did something right besides have a good manager.
