The song "I Think It's Gone Forever" by Merle Haggard is about a broken relationship that cannot be repaired. The narrator is speaking to their former partner, who has realized too late that their actions have caused irreparable damage. The narrator tells their former partner that they could beg and plead for them to come back, but it wouldn't make a difference because the love they once had is gone forever. The partner is hurt by this realization but the narrator tells them that they should have known better than to take the love they had for granted. The chorus repeats the idea that once something is erased or broken, it cannot be undone. The devil's wine is a metaphor for temptation or letting go of restraint, which can lead to irreversible consequences. The narrator tells their former partner that they can't forget the taste of what they gave up, and they will carry the wounds of their mistakes with them forever. Overall, the song conveys a message of regret and finality in the face of a lost love. The narrator has moved on, and there is no going back.
