When I hear public domain music in commercials. Even worse when it's catchy. DX Actually...Any music I recognize being in a commercial if I can't stand the song...Actually, any annoying song and/or commercials. Especially stupid ones. But if I hear game music in a commercial tben that's alright, as long as the commercial isn't absolutely idiotic.
Edit: Also, these fucking Peoples Jewelers adverts that keep showing up when using the Wii U's net browser! DX They completely fill the page without having any way to fucking close them, AND refreshing doesn't work! I have to go back a page, then manually click on whatever I clicked that brought me to the page where the ad appeared. GRRRRRR!!!!!!
