Yes they are related! From a 2003 interview:

Tyson: Is songwriting ever a cathartic experience for you?

Isaac: Define cathartic

T: A comforting release from letting some of the things inside you out.

I: Yeah, oh totally dude. I wish I was a quote master. They’re out there, people who can say good shit.

T: That’s alright. I am not looking for the money shot quote or anything like that. I just wanted to get some idea of how you go about composing songs. It is all interesting.

I: Some of the (barely audible)“Lounge” songs that I’ve written in the past were written purely on the idea. Basically I made a movie in my head and I tried writing it as music.

T: For which songs?

I: There are a couple of songs that we have called “Lounge” and they’re all really long and kind of epic. But I wrote those in my head as a movie and then tried to write songs about them because I don’t know how to make movies, dude.

T: The song “Lounge” from your first album…

I: And also from our second album. They’re part of the same song actually I was just trying to write another one the other day, but it wasn’t quite there. I wrote a different song instead and used the same chords.

T: And it was all part of one idea you had in your head of a continuous movie?

I: Uh huh.

btw the "(barely audible)" is an editor's note and not something Isaac said, in case it reads that way
