[MarioNintendo]

Sounds legit and indeed looks a bit more coherent. I know nothing about that notation though... I always thought what we had now was ok. :S

To how many songs does this problem apply to?

So far, I believe:

Maple Leaf Rag
Fig Leaf Rag
The Entertainer
Hungarian Dance #7
Tambourin Chinois (??)
Jelly Roll Blues
Turkish March
Black Key Etude
Op. 10 No.09
Mephisto Waltz
Grand Galop Chromatique
La Campanella
Winter Wind Etude
