Zach Bryan‘s backing off his recent Taylor Swift comments … apologizing to her legions of fans after he says he did some drunk posting on X the other night.

The singer-songwriter posted a pic of T-Swift’s album cover of “The Tortured Poets Department” … explaining he recently wrote he thinks Kanye makes better music than Swift because he drunkenly tried to compare two albums — and, it came out all wrong.

ZB says he was speaking strictly musically, and wasn’t cosigning any of Ye’s other beliefs … before adding he loves Taylor’s music too — and simply screwed up in his post.

In a follow-up post, Zach claims he’s been going through a tough time in his life … and projected his own issues onto Taylor. He says it came off as super rude — and didn’t embody the respect he has for the pop star.

Bryan says TS has been a force of nature for years … and, he offers some advice to fans too — encouraging them not to “drink and tweet.”

ICYMI … Zach deactivated his X account after tweeting out “eagles > chiefs Kanye > Taylor who’s with me” — basically saying Tay’s archnemesis is the better of the two artists.

Of course, Swifties were quick to react … calling Zach out for his comment — and forcing him to turn off his social media for a bit.

It seems Zach’s rethinking his music math now … and, laying on the apology pretty dang thick.
