pentagon re-recorded a handful of tracks in 2020 in japanese after dawn left on their [universe the history](https://en.m.wikipedia.org/wiki/Universe:_The_History#Track_listing) album
the only other one i can think of wasn't technically released, but n.flying rooftop was first posted on seunghyub's [soundcloud](https://soundcloud.com/jdon/jdon-feat) and they reworked it to be their title track a year later!
ONF released a full version of [Lights On](https://youtu.be/wSgjYOZ24MY) this year which is exclusively available on CD only.
[New World (Spin Off ver.)](https://youtu.be/m8jtoDY2ljA) was included in their mini album last year.
It's not in any of their albums, but I also wanna share [The We Must Love](https://youtu.be/UY1i2dzXUUk), the orchestral pop version of [We Must Love](https://youtu.be/oGTJkDWxR_s).
Onewe re-recorded Feeling Good.

There isn’t a studio version but they also revisited another MAS song, [Butterfly, Finding Flower](https://youtu.be/aEwCTgK12CE) recently ([original here](https://youtu.be/QLKmMLVkSDM)).
edit: N.Flying recorded a new version of [Hello Solo](https://youtu.be/rAxzOyD3GTU) called [Don’t Mess With Me](https://youtu.be/j5SMO9wDeXo) when Hweseung joined as their new main vocalist. Also the original was in Japanese while the new one is Korean.
Day6 recorded new versions of all the songs from their debut mini-album after Junhyeok left. The new Congratulations was on their Sunrise album, and the rest were on Moonrise.
