I hear that problem! I don't seem to have a lot of combat songs either (and the ones I have are mostly Not Appropriate for this context), or I'd rec you a bunch.

...so if you don't mind I'm just going to keep giving you songs that aren't quite what you ask for, WHOOPS. (well the last one kind of is! it's a barricade song at least, even if not for one of the particular moments you mention!)
