Detroit (CNN)Taylor Swift offered Aretha Franklin some R-E-S-P-E-C-T on Tuesday night in Detroit. "Last week we lost an irreplaceable force," the singer said. "Aretha Franklin did so much for music, she did so much for women's rights, she did so much for civil rights." Swift went on to say that Franklin "was one of those people where no matter what you said, no matter what glowing positive thing you said about her, it would be an understatement."
