Good call on Kickstart. I'm no Crue fan, but I can't disagree with that take at all. There are quite a few songs I feel have those anthemic "gang vocals," as you call them, and do them as well or possibly better. But it's hard to argue when the song is that iconic and well-known. But I'll name a few that come to mind below.
-DT - Profits of War: I hate the song. But the bridge/pre-chorus riff and crowd chant are pretty epic. And it was really cool of them to have brought in a bunch of fans to do that for the studio recording.
-DT - ITPOE: I couldn't mention Profits without this one. Same principle, even if they are a bit more understated and less important to the overall song.
-Trivium: Strife. This one is huge. Trivium has a few of these, but the one in Strife is what came to mind. It is such an OBVIOUS attempt to drop a huge arena chant into a catchy single, but it totally works.
