Liz Phair wrote that "'Spanish Doors' is "about the fracturing of a beautiful life, when everything you counted on is suddenly thrown up for grabs".
[1] Phair said that while she did "draw inspiration" from the divorce of a friend in writing "Spanish Doors", the actions described in the song were her own, explaining that "I relate to hiding out in the bathroom when everyone around you is having a good time but your life just fell apart...just a few moments ago you were a whole, confident person and now you wonder how you'll ever get the magic back.
labeled the song a "muddled mess", saying that the "strong verses and driving rhythm" were covered with "electronic beats, vocal effects, and layered chorus".
[10] In an Under the Radar web exclusive, Austin Saalman wrote of "Spanish Doors" as "a frantic breakup anthem not unlike something Phair might have recorded 28 years ago".
[12] Liz Phair performed "Spanish Doors" at an NPR Tiny Desk (Home) Concert, alongside a backing band of Connor Sullivan and Cody Perrin on guitar, Neal Daniels on drums, and Ben Sturley on bass.
