Martin Harrington and Thomas Leonard, along with their publishing company HaloSongs, claim Sheeran’s chart-topper sounds like their song Amazing, which was released by Matt Cardle, who won The X Factor in 2010.

The plaintiffs are represented by lawyer Richard Busch, who won $5.3 million for the Marvin Gaye family after proving Robin Thicke and Pharrell Williams song Blurred Lines copied Gaye’s Got To Give It Up.
