Tin Pan Alley grew out of the need for songwriters and song pluggers to demonstrate the tunes they had to sell to vaudeville and Broadway performers. Out of this came the classic songs of the Great American Songbook. If you want examples of songs that are written purely to be commercial which are good songs, then you will find them here in abundance.

Are you seriously trying to say, Dick, that Gershwin, Berlin, Porter and the like did not produce great music?
