What songs got their charts renewed on Cytus 7.0?

When Cytus got updated to 7.0, one of the changelog is

-Renewed charts for many songs in Chapter 1 - Chapter 3, providing new experience of epic songs.

^{(source on Facebook, Play Store, and App Store)}

but... they didn't provide the list of the songs which got renewed, which I believe its purpose is to make players curious and surprise them. However, this also gives confusion since not all players can remember the level & chart of all songs. To make it worse (well, maybe), the scores of those songs don't get reset. In the end, there's really no indicator everywhere (official website & in-game) if a song got its chart renewed.

Personally, I could remember most of Lv.9 charts (since I still need to get Million Master on them), and I did realize Chapter 2's Entrance got renewed chart (which is certainly harder now...). But how about the other songs? Could anyone provide a list of chapter 1-3 songs which got their charts renewed (and possibly, including the level change)?
