It's still rock and roll to me

(adj.) A way to show indifference to a given situation that has been altered. Taken from the song of the same name by Billy Joel.

Joey: "Hey, Steve. Sorry I forget to tell you, but the party at my house has been moved from Friday night to Saturday night. Will you still be able to make it?

Steve: Yeah, I'll be there. No problem. It's still rock and roll to me.

(Joey and Steve High-five)
