While I'm not a fan of Heart's 80's output, I'll always pause what I'm doing to listen to Ann sing regardless of the song.
Good call on Dreamboat Annie. The first song I ever heard from Heart was Crazy On You, and I was just knocked over with the vocals (not to mention the song rocks). As I recall I was sitting in our front room writing a book report on Fahrenheit 451 and listening to the radio on my mother's Motorola console stereo--anyone remember those? I didn't really sit up and take notice until the first chorus kicked in and I was instantly hooked. The next time it came on, later that day, I went and grabbed my older brother to come a listen to it. He and I pooled our money and went to the record store that weekend and bought the album. We shared that album for a few years and then he lost interest. I just naturally inherited it.
I purchased Little Queen, Dog and Butterfly, and Magazine (1978) as they were released, but from then on I'd moved on to heavier music and stopped following Heart.
Still, like I said before, my love of the timber and power of Ann's voice has never wavered.
BTW, Heart has a great Christmas album. Her performance on that album is as great as anything she's ever done.
