I have three different recordings of Satie's Gymnopedies on CD from many years ago: de Leeuw's, coming in at almost 16 minutes total; a version from 1968 by William Masselos totaling about 9 minutes; and on the extreme end, Klára Körmendi's version totaling less than 7 minutes.

When I used to play piano, I once timed myself playing them to my own preference. As I recall, it was around 11 minutes at the speed that makes sense to me.

Chacun a son gout. (Satie himself claimed to only eat foods that are white, after all.)
