Sam OK, here are the top 100 I came up with from the Carnegie recital database.
A friend of mine put together a dataviz for performances by the NY Phil. Beethoven wins there, with Mozart, Wagner, Tchaikovsky, and Brahms rounding out the top 5.
Stub Of the top twenty you show in the graph, I've played at least one piece by 13 out of the 20 composers.
18/20! (missing AlbĆ©niz, BartĆ³k) Only around 30/100 overall, although I guess I've been learning a lot of stuff outside the top 100
