<P> A pop and R&B ballad , the subjects of `` Best Thing I Never Had '' are revenge and karma . Not wanting to feel broken - hearted , the female protagonist sings that she feels happy to have left her lover , who did not recognize the potential for a happy life with her . Some critics viewed it as a sequel to Beyoncé 's 2006 single `` Irreplaceable '' as the two songs are thematically similar . However , some lyrics , including `` showed your ass '' and `` sucks to be you right now '' , were criticized . The ballad was also likened to Vanessa Carlton 's 2002 single `` A Thousand Miles '' ( 2002 ) . </P>
