What verb + other basic stuff.

1. What verb would I use to say that a song matches a person perfectly? Would it be 似合う? This seems related to clothes though, maybe just 合う? Different altogether? Or does it even matter what matched what? この曲はその人に ??? (なにがここに入れますか？)

2. And could I then use きっちり or かっちり as an adverb with a meaning of "perfectly" (Any huge between the two?)

3. I know adverbs can go anywhere before the verb it describes (within reason I guess), but just to check, would it sound natural placed in any of these two places:

この曲はきっちり、。。。
この曲はその人にきっちり。。。

Basically I was gonna comment on a video but then didn't because I realized that I literally have no idea how I strange I may sound.

よろしくお願いします：）

なにがここに入りますか？;-)
はいる: intransitive
いれる: transitive

1)
They both can be used. The nuance/context which should be used are a bit different, though.

2)
ぴったり is most common.

3)
Both are OK.


When この曲 and その人 are obvious from the context, i.e., probably in most cases you comment on a video, I would just say ぴったり！

Thanks for the reply, and thanks for the correction. I just went and looked at lists of pairs again. Whenever I write anything I will check these next time...

Okay, say I did actually write the whole sentence, including the song and the person, would it sound wrong? (not technically wrong, but excessive/awkward?).

I have no idea of how it would sound.

Not wrong, but "how natural it would sound" totally depends on the context or the sentence. Even just to add は to the sentence sometimes breaks the naturalness.

Yeah, I see what you mean. I guess something like this is something I can't just get one answer to and be right everytime. I'll just have to read and listen focusing on how people use the language and get used to this "naturalness" myself. It'll be hard but I will get there hopefully someday lol.

And Toritoribe, again, thank you so much. I truly am grateful for your constant selfless advice and help with my Japanese. You are amazing! 本当にありがとうございました！
