Some Mexican guy is listening to some pop mex crap and I’m going to remember it? I remember the scene. Don’t remember the music. Might have remembered it if it was something I knew. Maybe even some Tex/Mex by Freddy Fender.
The most memorable song in either Saul or Breaking Bad was ‘El Paso’ in the ‘Wicked Felina’ episode at the end of Breaking Bad.
The music in both BB and Saul was consistently excellent. Same with visual elements. Very high production qualities.
How about;
HOTEL CALIFORNIA
in The Big Labowski?
