Our Constant Concern is the second album by American indie pop duo Mates of State.

Mackenzie Wilson of AllMusic called it a "stunning follow-up to 2000's My Solo Project," praising the duo's mixture of "sugary pop hooks" and "deep lyrical conversations" through "young but charming" harmonies, concluding "[T]heir relationship is their musical storybook and Our Constant Concern playfully suggests that love can really be beautiful.

"[1] Pitchfork writer Rob Mitchum was disappointed with the album, noting the slow tempo of the material, heavy use of non-distorted organ effects, and the duo's harmonies being "far less eccentric and less vibrant" compared to their first effort.

Despite giving praise to "Quit Doin' It" and "Halves and Have-Nots", he wrote "these brief flashes, even on a thirty-minute album, do little to keep the dreaded sophomore slump virus from hitting Our Constant Concern.

"[2] The Mates of State song "Girls Singing" from the Our Constant Concern album was prominently featured in "Changes: You Got A Prom Wit Dat?"
