There's a big difference between having a raspy/rough sound and being strained/choked. Janis Joplin used a raspy sound as a choice, and she kept an open throat throughout. There are recordings of her singing broadway songs and her belting range is crystal clear, no raspy sound at all. Christina on the other hand, she can ONLY belt out with that choked/raspy ugly sound.
