Puritan guy here. Perhaps a few of the different lyrically tracks spread out across an album. Only a few tracks off each album ever stay consistently in a setlist as fan favorites anyhow right?
don't over think it/generalize. sometimes a song just turns out the way it is as does the album. puritan was written when i was 16. the best days are now. last album every topic is different, same as the album before, all diff topics ranging from anxiety, mass media, suicide, drug abuse/addiction, abusive relationships, ocd, karma, past lives, reincarnation etc
