If you read my post properly you will understand what I mean. The answers to your questions are already there. I'm not "complaining", I'm just giving my 2 cents of what would make a player more engaged to the scenes when playing.
I'm not complaining about the music itself, but the sound variance on the scenes. That's why I didn't ask for a difference OST (because it isn't bad) and mentioned sfx like birds, wind, trains, etc. It gives ambience to the scene.
That's why I mentioned Super Mario, because it's one of the few songs in gaming industry you won't get tired of. I don't dislike the OST itself and I don't want it to be changed by any means, just think more variance for the player would be nice to make him hooked into the game and story.
But to answer you question more directly about music, when I get tired I change music. But I don't get tired in 3 months because I don't listen to the same song over and over. Fortunely I'm not one of those guys who fell into the despacito trap "listen this, listen this". Adds do nothing for me, I like to search my own music, and I believe I have quite a decent taste in music. But I don't want to spread the off topic, and like I said, the issue was never the music in the game. The music itself isn't bad, but after hearing it without ambience it can be tiresome after some time playing. That's why I mentioned I never felt that when I played the very first release, only noticed when playing for longer content. Just gave my opinion because I like the game. I tend to focus more on commenting on stuff I don't like on games I like than wasting times on games I don't. Because I want them to succeed.
