Oppose Popular music is an odd intersection of art and commerce, where "breaking the rules" is accepted practice.  It is also accepted practice here at Wikipedia, per WP:IGNORE.  We should be embracing complexity and reflecting it accurately, not working to over-simplify and whitewash over it.  We need to leave this article name alone, strengthen the "loophole" that has got some of y'all's undershorts into uncomfortable positions, and then rename Kesha to Ke$ha just to prove the point.  Otherwise, we'll be on the slippery slope toward renaming Madonna (entertainer) to Madonna Ciccone because "any reasonable person would expect her to have a last name."
