I think the driving music and the office music are both variations on the same theme. And that tune from Pounding Fathers plays a lot at the end of the cases in the first two seasons. The first time was near the end of 102 when they go on Myra!. There was something in the musical commentary about it. I can't remember exactly what it was, something about how it was supposed to sound like a band on the set was playing it.
Did people notice for instance that the music in the clone chamber in 305 is a very extended and Jamed Bondified version of the same theme that plays whenever Flint crashes into a room in season two?
I didn't! But I haven't listened to the Devil's Playhouse music that much.
Here's a list of musical references that I know. There's only a few from season 2 because I don't feel like looking through all the cutscene suites right now.
-The music that plays in the final battle in 101 (Attack the Dog) is a more sinister variation on the first season opening credits.
-The music in front of the Black Hole is a more subdued version of the music to Hugh Bliss's
inner sanctum in 106.
-The Soda Poppers have music associated with them. The best song on the soundtrack to hear it is Rushmore, Lush, War (I didn't notice they had theme music until my second or third playthrough of the first two seasons, shut up)
-The music that plays whenever Jimmy does something is very similar to the Whack-A-Rat music from Hit the Road. You can hear it on the first season soundtrack in Skinbodies Rule The Streets and Whack Da Ratz.
-The music on the White House lawn (Lincoln vs. Max) is an arrangement of Hail To The Chief. Pretty obvious if you know the song.
-The music in the Oval Office (Consecutive Offices) is apparently a super jazzy version of the Star Spangled Banner, but I don't really know the tune, so I wouldn't know. It also becomes more sinister when Max becomes president.
-The music that plays when Bosco gives you the truth serum (неудобство) is a muzak version of... a Russian song I don't know anything about. But I know that it is.
-The music in Banco Lavadero is an 8 bit version of the music that often plays when Sam and Max solve a puzzle.
-The music on the moon (Moonscape) plays briefly whenever you try to launch a missile at Bosco in 104.
-The opening credits music in the second season is from the music that often plays during final puzzles (Freelance Panic).
-The music at the North Pole (Arctic Hush) has some of the melody of the Carol of the Bells.
-The music in Jurgen's club (New Location Unlocked (Midtown Cowboys Remix)) has some of the melody of the Midtown Cowboys theme. It's most obvious from about 2:45 on.
-The music that plays in 305 when Max sacrifices himself
is a sadder version of
the music that opened every episode of the second season except the last. I'm not sure if it's right at that moment, but I know it's in that scene.
