PIPES OF PEACE also contains "So Bad," a beautiful, smoldering love song that is arguably one of McCartney's most underrated ballads. Though McCartney tries to deliver a big message on the title track, PIPES OF PEACE works best as a pop album and it features a fine mix of upbeat songs and earnest ballads that give McCartney ample opportunity to show off his incomparable voice and peerless musicianship.
