Olivia Rodrigo's Christmas song sounds familiar... on purpose

In the end, he decided to reply to her email - and posted the text to his Facebook profile.

"If you really are you, thanks for contacting me. And your comments are really sweet, and very flattering," he said.

"They're really sweet and flattering... even if you AREN'T you.

"If you really are Olivia Rodrigo: I like you, I like your music. I like the arrangements especially. Soft-loud-soft, etc. And that your recordings sound like people are playing on them.

He continued: "I like that your lyrics are intense, real, and poetic. I like that you "got" my songwriting, and that you like our band."
