Tin Pan Alleyite

A “Tin Pan Alleyite” is someone who worked on the historical Tin Pan Alley on West 28th Street, or who works with a Tin Pan Alley-type of music publisher, or is a fan of Tin Pan Alley-type music.
 
“Now, ‘Tin Pan Alley’ is considered a term of reproach by the Tin Pan Alleyites” was printed in the St. Louis (MO) Post-Dispatch on May 10, 1903. “When it comes to writing a comic song there is no Tin Pan Alleyite who has anything on Eddie Moran” was printed in Variety (New York, NY) on January 9, 1909. “JAZZ SONGS LOSE PEP TOO SOON, SO TIN PAN ALLEYITES DECIDE TO GO BACK TO ‘SOB’ STUFF” was printed in the Pittsburgh (PA) Post on November 5, 1919. “He was a true Tin Pan Alleyite (although there is no such word) for he was typical of those who would constantly worm their way into a publisher’s office, or meet an associate at two in the morning at some dimly lit café to write a song” was printed in the book American Popular Song Composers: Oral Histories, 1920s-1950s (2012) by Michael Whorf.
   
“Broadwayite” is a similar term for the theater.
   
   
Wikipedia: Tin Pan Alley
Tin Pan Alley was a collection of music publishers and songwriters in New York City which dominated the popular music of the United States in the late 19th and early 20th centuries. It originally referred to a specific place: West 28th Street between Fifth and Sixth Avenues in the Flower District of Manhattan; a plaque (see below) on the sidewalk on 28th Street between Broadway and Sixth commemorates it. In 2019, the New York City Landmarks Preservation Commission took up the question of preserving five buildings on the north side of the street as a Tin Pan Alley Historic District. The agency designated five buildings (47–55 West 28th Street) individual landmarks on December 10, 2019, after a concerted effort by the “Save Tin Pan Alley” initiative of the 29th Street Neighborhood Association.

“TIN PAN ALLEY?” WHY IT’S THE PLACE
WHERE THE POPULAR SONGS COME FROM
(...)
Tin Pan Alley is that part of Twenty-eighth street that lies between Broadway and Sixth avenue. Here center the song-publishing houses of New York.
(...)
Now, “Tin Pan Alley” is considered a term of reproach by the Tin Pan Alleyites. They prefer to designate it as “Melody Lane.” But this is a poetic fancy that those who go down that way to hear the “new, big, screaming hits” do not indulge in.
