The context is this tweet:

> **セットリストに適当** ！って書いてます。笑

I could understand more easily if は was used instead of に. How does に change
the meaning?

Does an inference have to be made here to understand what is appropriate?

question
particles particle-に
Difference between AにB and AはB
`に` means that the action is being directed at the subject in question. `は`
means... well, `は` is defined as a "topic marker", but trying to really define
its usage is a whole topic of its own.

Anyway, `適当【てきとう】` in this context means "flippant", and so the speaker is
being flippant _toward_ the set list. In English I think the more natural way
to say it would be that the speaker is being flippant _about_ the set list.

`セットリストは適当` , in this situation, would mean that the set list itself is
flippant somehow, but it would be vague about why, who made it that way, and
how exactly.

I think this person (maybe a musician) just means:
