Should the ending song change?

I think the ending song (Good Habits) should be changed because it sounds something like from a Don Bluth production or another children's movie. Should it change? YES/NO? What would you think the song should be if it is changed? For me I would like it to be an abridged version of HEYAYAYAYE!!! Canon in D by Johann Pachelbel (classical music) or even a reprise of the opening. Its still good though.
