My first reaction was reflected in the Rolling Stone article linked above:
The song was really kind to the character because it intimates that, despite all of Walt's horrific behavior, he was always just a chemist at heart. I thought it was a deliberate choice to ignore the "He had it coming lyrics" in favor of "He made his own choices". I neither felt bad for Walt, nor good that justice was done - either of which might have been what I expected. In a weird way, it struck me as a happy ending for the show.
