If a copyright lawsuit is successful, Ed Sheeran claims he is “done” with music.

One of the top musical acts of his time is the English singer-songwriter, Ed Sheeran. With numerous albums and singles that reached the top of the charts, the Grammy-winning “Shape of You” singer is one of the best-selling artists ever.

But right now, a lawsuit threatens to end Sheeran’s career at the height of his fame; if he loses, Sheeran has declared that he is “done” with music.

The estate of Ed Townsend, who co-wrote Marvin Gaye’s 1973 soul song “Let’s Get It On,” is suing Ed Sheeran. According to AP, the lawsuit claims that Sheeran’s 2014 hit song “Thinking Out Loud” contains “striking similarities” to the previous song and thus infringes copyright.
