19 isn't part of Sony, but Sony used to have a tie to Idol.
2010:
Quote:Universal Music Group has won the rights from 19 Entertainment and "Idol" creator Simon Fuller, shifting the reality hit’s record deal away from Sony.
...The Sony collaboration helped spawn hits for Carrie Underwood and Kelly Clarkson...
Casey James was signed by Sony Nashville and Kellie Pickler was with them until last year. So I can understand how someone in the country music segment who doesn't have a complete understanding of the big picture might think there is a tie between 19 and Sony.
