Here are mine:
1. Kinght Of Firmament is harder than Parousia.
2. Fable is the third hardest song in the game. It's even harder than Imagining.
3. Reverse-Parallel Universe is an easy lv8.
4. Little Corgi's Dream is too hard for a lv8.
5. Leviathan is quite easy for a lv9.
6. Witch's Invitation should be a lv9.
7. The Red Coronation is easier than Precipitation.
8. Sanctity is only about lv7. Same goes for Pilot.
9. Platinum is way too hard for lv6.
10. Pure White normal is harder than Entrance normal.
Here it is. Hope you will not kill me...
