I recommend "Microcosmic" with touching lyrics.

The message that we become each other's universe is truly beautiful. The members' voices blend warmly, adding to the emotion. It is a song that fills you with even more emotion when heard at a concert. The lyrics are as beautiful as poetry, so the more I listen to it, the more I like it. It makes my heart feel warm the moment I hear it. It is a song that can comfort you even on tough days. It is a song where you can understand why it has been loved for so long.
