For those who don't think Elvis Presley was a good singer, go to YouTube and listen to these Elvis songs:
"From Rags to Ritches"
"Stand by Me"
to name a few.
He was an underrated singer by many as they only heard songs like Jailhouse Rock or Hound Dog. Elvis also did a number of gospel songs and, in fact, his only three Grammy Awards were all for gospel songs he sang. He still has millions of fans all over the world who think he could sing a more variety of songs than most singers of today.
