Ed Sheeran co-wrote “The Rest of Out Life” for Tim McGraw and Faith Hill and now they are headed to court for a copyright lawsuit.

The complaint was filed yesterday by two Australians who say the track is “blatant copying” of their own 2014 song, “When I Found You.”

The complaint states, “The copying is, in many instances, verbatim, note-for-note copying of original elements of the Song, and is obvious to the ordinary observer.”

The lawsuit also presents musical transcription excerpts of each of the songs to make the case of substantial similarity. Both songs are said to explore themes of marriage, the passage of time, aging, and the way that the romantic relationship protects the speaker against vulnerability.

The Australian writers are seeking injunctive relief and at least $5 million in actual damages plus profits, a running royalty, and an award of attorney’s fees and costs.
