Jason Mraz was left stunned by a Nick Jonas tune performed in the Disney TV movie CAMP ROCK 2: THE FINAL JAM - because parts of it sounded just like his hit I'M YOURS.
The singer is convinced the acoustic track, Introducing Me, was inspired by his own Grammy-nominated tune - but the laidback star insists he can't be bothered to take legal action over the matter.
He tells PopEater.com, "I heard the song, and it was just a tremendous, tremendous horror of a tune.
"I noticed a few similarities in the melody, but it wasn't enough to pick up the phone and argue with somebody about it. If anything, I just wanted my $1.29 back that I spent on iTunes."
