I'm a fan of Enya and Clannad, and just recently have expanded my collection to include other contemporary Irish and Celtic music. I had heard more of Sinead O'Conner than actually listening to her. And so on my first listen, I found her good, enjoyable. But second time around, I heard so much more in her voice, and her messages. I did find it useful to be aware of the source of each song in order to better understand her and her development. There are four songs from her debut which introduced a startling and strong voice, possibly an angry one: Mandinko; Troy; I Want Your Hands (on me); Just like U Said It Woud B. Indeed, these songs are unexpectedly fresh and new.
Then from "I Do Not Want What I Haven't Got," an album re-inforcing the impact of the first, though a bit more controlled, you have: Nothing Compares 2 U; The Emperor's New Clothes; The Last Day of Our Acquaintance; I Am Stretched Out On Your Grave. These songs do show development, and the last of the four is my favorite because I was impressed with the traditional flavor which I wasn't expecting.
From "Am I Not Your Girl?" we have "Success Has Made a Failure of our Home; and "Don't Cry For Me, Argentina." Great as these two are, one feels this album disappointed some of her fans because of the more familiar material.
And "Universal Mother" apparantly was much more mellow and controlled than many of her fans were expecting or wanting, and yet if "Fire On Babylon" and "John I Love You" are examples, I'm sure I'll eventually add it to my collection.
And so you have the impressions of one who wasn't really expecting to become a fan of hers.
