So to answer the question, who's still creating good music today? Tons of people. Stop listening to the radio and actually go looking for it.
For clarity's sake, the question wasn't "who's still creating good music" - I'm a huge fan of contemporary music. The question was "who's still making music in the same league (for lack of a better word) as Bach, etc." But yeah, that question doesn't really work - Bach has been dead for centuries, we don't know, yadda yadda.
