magnum opus
/ˈmæɡ.nəm ˈoʊ.pəs/
CommonThe greatest or most important work of an artist's career.
Carries weight because it is a judgment about an entire career, not just one release. Using it too casually makes it meaningless. Sometimes deployed ironically for obviously mediocre work.

Use it when
- Calling one album the definitive peak of an artist's entire output.
- Debating which project best represents an artist's legacy.
- Praising something as career-defining, not just good.
Do not use it when
- You just mean your personal favorite album by that artist.
- You mean a good recent release, not a legacy-level statement.Use “banger” instead.
- You are talking about a single or EP, not a full body of work.
