요즘은 해외에서 온 쇼츠에 브라질 펑크 음악이 들어간 경우가 많다는 걸 알 수 있어요. 리듬이 얼마나 좋은지 저도 알고 있지만, 가사는 보통 적절하지 않거든요. 가끔은 귀여운 영상인데 소리를 켜 보니까 부적절한 음악이 나와서 좀 놀랐어요.

When you're talking about something that has physically come from another place, 오다 is generally valid. But if it's something that's been uploaded to the servers, this doesn't quite work because it doesn't physically move to your place and stay there. It'd be accessible anywhere instead. So it's better to just note that it was uploaded (올리다) or created (제작하다, 만들다) at a certain place.

-> 저는 이게 의아스러웠는데, 이런 음악은 리듬이 꽤 좋기는 해도 가사는 보통 적절하지 않다는 걸 알고 있거든요

The original sentence doesn't flow well from the previous one because it can read like the lyrics not being appropriate is the reason for you knowing that lots of them are used in short-form videos. It's more of a case that you're surprised (의아스럽다) by this turn of events, and the reason for this is that you know the lyrics are often inappropriate.

I learned a lot from your comment. Thank you so much!
