I LOVE that this thread exists. I guess I'm not the only one who immediately thought of Nolita Fairytale when I heard it in Dear California!
I really like both, I think they were created to fit the song perfectly. Nolita Fairytale is very lively and strong, so the loud "HEY!" and the echo works great, whereas Dear California is much more mellow, so the soft "hey" that soon gets overtaken by the guitar is perfect.
