Its a bit of a impossible question as the 3 areas arent entirely exclusive. Like if you pick movies, your movies wouldnt have any musical score - and of course no musicals like that ghey abba movie

Your music wouldnt have music videos and your games wouldnt be allowed music or pre-rendered cut scenes.
Regardless though id choose games with music a close second. Even though i love music i could live without it and some radio shows would still be good entertainment without music. The majority of movies are awful and totally uninspiring etc anyway so i dont think id miss not watching them, add in television shows and it becomes a little closer. Overall though i enjoy games more.
