I am not absolutely convinced it has to say something, although it depends on "what something is." Look at Camptown races...Camptown ladies sing this song, doo dah doo dah Camptown racetrack five miles long oh doo day day. That song has survived but I am not sure what exactly it says..maybe a description of an era.. maybe it just gives a visual picture..or the Beatles..Oob la di...I guess another visual picture of a working class marriage and a trip to the market..well, that is the picture I get...I don't listen to words that well..I don't think songs have to have a message though if that is what you mean..mg
