As I say; you really have to spend to get better sound than the Shure Brothers make. You have an interesting website. The birth of the popular song occurred as a result of Piano Rolls being 3.5 minutes long. The songs had to be written to fit one roll. Since Player Piano technology parralled the Gramaphone the Piano Rolls usually ran about 7 ft per minute wich would reproduce one side of a Gramophone recording in 3 minutes. That is where we get the 3 minute time for the average pop song. Then one side of a 78 is 3 minutes and that was reproduced by the 45 single. Early popular songs written before the Player Piano would sometimes exceed 10 minutes or more for a ballad.
