Tom Petty says it's a continuation of "Wildflowers". Believe or not, "California" and "Hope You Never" were recorded and intended for "Wildflowers". "Walls" and "Angel Dream" are two of my all time favorite Tom Petty songs. "Angel Dream" is the perfect song to sing to the girl of your dreams(but seeing as I haven't had one for 17 years, I haven't been able to sing it to the girl of my dreams, have I?).
