My brain made the connection between two opus 80s in F minor: the Prokofiev Violin Sonata and the Mendelssohn Quartet. Naturally I would collect other 80s into a playlist:Bach, Cantata 80 "Ein feste Burg"
Prokofiev, Violin Sonata, Op. 80
Mendelssohn, String Quartet, Op. 80
Beethoven, Choral Fantasy, Op. 80
Britten, 2nd Cello Suite, Op. 80
Brahms, Academic Festival Overture, Op. 80
Haydn, Symphony #80 in D minor
Faure, Pelleas & Melisande, Op. 80
Myaskovsky, Divertissement for small orchestra, Op. 80
Sibelius, Sonatina for violin & piano, Op. 80
That will keep me occupied for a while. I was surprised how many familiar pieces cropped up in the Bs.
PS - if you don't know it, the Prokofiev is a very good thing.
