Most bands get around this by taking horror tropes and not actually making the video scary. Which isn’t a bad thing! I’m all for comedy videos involving zombies or vampires! And this category actually gives us some interesting examples. T-ARA’s song “Lovey Dovey” is in this nebulous area where it’s mostly a comedy video but it plays with horror and zombie tropes to give a sense of unease, especially at the beginning. It’s also meant to be a callback to Michael Jackson’s “Thriller”, which has comedic elements as well (though I’d argue it’s mostly straight horror.)
Even so, despite the general sense of unease, “Lovey Dovey” is more funny than scary. The girls continue dancing as zombies attack, until they’re eventually overrun. Then afterwards, they still continue dancing, and they’re still pretty cute zombies with minimal decay. It’s not a very frightening video, it’s just good fun. And that’s all right too! I love “Lovey Dovey” with all my heart.
