That issue is.....Are the songs in stereo actually in phase. I have found various hit songs on various major label cds that are out of phase to varying degrees. Sometimes the same exact song is somewhat out of phase on one cd and in phase on another cd. The worst example of an out of phase song is "Walk A Miles In My Shoes" by Joe South which is totally out of phase. I would be interested in any examples of out of phase stereo versions of songs from the 50s, 60s and 70s.
