Hardest piano song EVER....

I Guess Feux follets and Grand gallop chromatique are a song dat needs a lifetime dedication to be playyed . Damn hard .. Bout grand gallop , it require a very supple wrist in both hands and a very very precise accuracy of striking a note distinctly and Hard.. it's a damn hard work .Harder than Fast moving note, Not more than 5 people in dis world nowaday can play it perfectly i suppose ...
N bout Feux follets .... I guess it's the really Transcendental one ... What A Right hand "kind of Double note tremolo" ...Liszt fingers is really like a magic ... I wonder how Liszt played .. He's really a Magic..
Maybe all piano player will be desperate after seeing Liszt playing ...
