Big Willie Like do they not have a music department that can come up with different music in each episode based on what's actually happening rather than putting in their template instrumental everywhere.
Going back to what you were actually moaning about - this is exactly what they do. For example, the OST for season 1 has 26 songs composed by Nicholas Britell. Many of them borrow elements from the main theme, which he also composed. For example, if you check out this song:
It's clearly a different song, but with similar elements from the melody of the main theme. If anything, the music is much more thought through and less generic than in most shows. That's what I responded to, that you seemed to think they just lazily played the same song over and over again. But they're different variants.
So regardless of whether you like it, which is fair enough either way, I just want to point out that a lot of thought has definitely been put into it.
Some interesting bits from an interview he did after season 3:
The show's musical signature is its mix of "dark, courtly classical sound" with "oversize hip-hop beats and 808s," with the latter reflecting the taste of both protagonist Kendall and real-life hip-hop enthusiast Britell.
And it's meant to sound "off-kilter." Britell says he gets asked whether the piano and strings are supposed to be out of tune โ and the answer is always yes.
"I have takes of some of these things where it's perfect and it does not sound right because when things sound, quote unquote, 'right' for the Roy family, it's wrong," he adds. "It doesn't work because the family is so dysfunctional that the music has to have this kind of brokenness to it somehow."
Britell's Succession repertoire includes far more than just the opener. He says he does five to 10 new themes every season, in addition to variations on the main theme chords, which was part of his conscious effort to evolve the music throughout the show's four seasons.
"I had this framework, it was kind of like an early thesis of, well, what if every season was a little bit like a movement of a classical symphony?" he explains, adding that each has its own "emotional hue."
Season one, like the first movement of a classical symphony, was an allegro: "You're setting out a certain set of ideas in perhaps a slightly quicker tempo." Season two was an adagio, or a "slower, more inward, more introspective kind of a movement" (inspired by Kendall's arc). Season three was a lighter scherzo, which comes from the Italian word for joke.
