Can you add your own music to a smart TV? Like play your own music on it?

I have a Philips led smart TV and it comes with pandora and a lot of other apps and games, but I was wondering if I could play my own music on it from my iPhones playlist/ itunes playlist? Or is it a way to get more apps or it is pretty much only allowed the apps that come with the TV?

Through a USB Flash Drive you should be able to, I have a Vizio and I can do it, and there should be an app store to add apps.
