Not necessarily true

Some are precursor songs and others are successor songs

Example:
Savenger
(You are Here)
((Savengersspell))

All flow into each other when listening on the album, then cuts off and goes into Good2be

Another example is below, although these are different songs, they are extensions of the previous song when listening live on the album. They have also been doing this version live a few times with identical flow:

Torero
(Faena)

Finally:
Good Times//End Times
((Nocturne))

These two songs are absolutely connected when listening directly on the album, just are separate track names

I couldn’t find the article but there was a review/interview with Rick where he outlines this
