You guys have a featured Chopin playlist (great idea!) but it's missing an excellent work by Chopin, Prelude 24 Op. 28 No. 15. It might be missing other excellent works by Chopin but I wouldn't be able to tell you as I am not the expert in this subject. This work is in the top 10 songs under "Popular" when you are viewing Chopin so please consider adding it to his featured playlist, thanks!
