Lyric discussion by Pac 

Cover art for On & On & On lyrics by Streetlight Manifesto

The little Pachelbel's Canon homage just really combines with the lyrics to really make me feel good when I listen to this song.

Even though it's really about coping with horrible shit going down, musically it's uplifting.

Noticed that too quite recently (been listening to the song for ages) , i think that its a reference to the fact that even though now is shit it'll be better and there'll be a wedding (or another joyous occasion). He's essentially expressing the lyrics in music form
