I find it humorous in light of the article that we would be having a debate over any question of categorizing her when she has stated that she will not do so (I see no "plea" but the implied plea to let the issue alone).  Leave the little section in the article invoking the controversy, and let her keep her mystery going (at this point, any conclusion one might draw after reviewing her music as she suggests in the interview would by definition be opinion, synthesis, and OR; fun, but not appropriate for encyclopedia).
