NASHVILLE (AP) — Old Dominion are finding that one little song is changing a whole lot of hearts. Singer Matthew Ramsey says they hear all the time from couples who are together because of their song, “Break Up With Him.” They also hear from the exes, but not directly. Ramsey says they’ll get thinly-veiled tweets, and guitarist Trevor Rosen says they’ll say things like, “Nice SONG, bro.” Ramsey says his reaction is, “I know what happened to you!”
