BEMANI songs influenced by the 2011 Tohoku Earthquake

Lately I've noticed more and more songs in recent BEMANI games that have been influenced by the aforementioned disaster. As obviously this is a great platform for all of the artists to express their feelings about something bad that could have affected their personal lives or perhaps their friends and loved ones lives too.

So I'd like to make a list of songs that have some or all influence from the earthquake, and perhaps would not exist had it not happened.

Tohoku EVOLVED / 2.1MB Underground (Obvious)
F / D.J. Amuro (Music notes state this song was produced around the time of the quake, so the name was given to reflect the "lowest level" in IIDX)
DIORAMATIC MOMENT / TЁЯRA (I recall Naoki mentioning the importance of the song on Facebook before the release of ЁVOLUTIФN.)
陽炎 / 星野奏子 (Possible inspiration in song lyrics)
Into the Sunlight / Kobo feat. RIO (Lyrics and tone of song were changed after the earthquake)
Lucky Days / Sota Fujimori feat. Kanako Hoshino (One of the first songs recorded right after the earthquake)

Any others that may have an influence? Either as noted by the artist, or even if you just have speculation, I'd like to see it.

There might be some hints in music comments of DDR X3

REBORN MAGIC, New Beginning, アルストロメリア (walk with you remix)

Artists all mention 2011 as a difficult year, especially seiya-murai, who write the song hoping everyone can break the wall and get up again.

The original "アルストロメリア" plays in a sad mode. "walk with you remix" makes it much brighter, so these two mixes finally become a complete set.

except that Broken debuted in REFLEC BEAT which was released in 2010.

To be honest these fits more in the interesting things in DDR (but why is it DDR only) thread...

Weird, I don't find アルストロメリア to be sad. It and its remix sound similar in tone.

I have to agree, Alstroemeria is quite blissful, I mean come one the album jacket has a smiling girl on it!

the happy memory/moment of a place you visited before?
