One of the two major ingredients of a good song or story is 1. Specificity. Images you can feel, taste, hear, see. 2. Language that is direct and singable. 3. A sense of "place". ( Jean Ritchie and Woody Guthrie capture these elements admirably. Or the writers in the past like Irving Berlin, Johnny Mercer or Yip Harburg) 4. Defining who is singing and/or to whom.

It doesn't matter which persona you use if you have these elements.

For me there is 5. A variation from the verse to the chorus either in music or in stanzaic
form.

Eric Bogle's "Band Played Waltzing Mathilda" is written in the first person.
John McCutcheon's "Christmas In the Trenches". They probably haven't experienced
what's in the songs personally. That doesn't matter.
