BACK TO THE MUSIC Instagram / @zachlanebryan
While Zach Bryan's ex-girlfriend is on the bathroom floor crying about their recent split, he's putting out new music ... and it has the makings of a breakup song.
The musician just shared a snippet of a new track on his official Instagram page ... and he's banging away at the piano and singing.
Among the lyrics ... "Recall when we, went to Rockaway Beach, summer heat in eastern Queens, and a subway ride."
"COMPLETELY BLINDSIDED" Plan Bri Uncut
Zach also turned the comments off on his IG post .
