Once upon a time, there was a group named Dumhi and one of its members was named Shameless Plug. The rapper eventually opened himself up to sing more and things were left as is. Then he decided to widen his scope, which meant he would change his name. Welcome yourself to Charles Only, which is based after his real first name so if you have never heard of Shameless or what he did before, then get yourself familiar with Charles Only. “Blue Checkmark” is a nice soulful track he did with producer Nemes1s and with luck, this will be the one that will take him to the next level.
