I've found 2 great music scores today, and both scores are Beethoven's masterpiece, which also my favourite.
The first one is
Sonata No. 8 "Pathétique" (3rd Movement: Rondo)
Sonata No. 14 "Moonlight" (3rd Movement: Presto agitato)
The 1st one is the song "V3" in O2 Jam.
The 2nd one is the song "Mad Moon Sonata" in O2 Jam.
Here's midi sample of those songs.
