That anon again. It's cause Finnish intrigues me. Outside of those languages, I've also looked a tiny bit at Japanese and Gaelic, and have a passing interest towards Romanian, Russian, Portuguese, and a smattering of random endangered languages. I just find languages interesting, and media I find interesting IN a language makes it much more motivating for me to try to learn.
As for Finnish/Hungarian, there are some other things I've bumped into here and there that contribute, like Finnish internet memes in-general, or A kockásfülű nyúl for Hungarian (Not a lot of speech-heavy Hungarian stories, eh?). If not for those, I'd most likely not even try.
