I've noticed that some songs' titles appear in the lyrics to of other songs (such as the line "home again" appearing in 987, "do what you want to do" appearing in we could just get high, etc.) Are these intentional references to your other songs or just coincidences?
neither. the english language surely has a finite amount of words and phrases available. even fewer if you only consider 'normal' phrases. which i use exclusively for my music, as part of the normal genre
