I've never been the greatest music fan. Sure there are tracks I like, singles I like, but I've never been one to follow a particular artist through thick or thin. In my first year at University in the UK I met a Canadian from Vancouver who had more CDs than I had ever seen in one place at one time. In his collection I found this album and quickly went out and bought my own. His obsession with VW cars I have forgiven, the introduction to the Onion I have elsewhere acknowledged, my lifelong addiction to this album I now admit.
I don't know what it is. Other singers have equally great voices, other musicians have similarly great ability, other lyricists make you ponder as much. There is just something about this album that I love. Whatever mood I am in, from bleak recently dumped depression to uplifting joy, I can play this album and it is appropriate. I like other tracks by Sarah McLachlan and own her other albums; tastes change and other artists come and go but no matter what I listened to last this album is suitable next.
You may be looking for a detailed analysis of musical metre, verse structure or beat arrangement. I have no idea about any of these things (and may have made at least one of these up). What I can say is that this is a superbly personal album from a female singer songwriter that has touched me from the moment I first heard it almost a decade ago, and continues to thrill, excite and sustain me to this day. Give it a try. Then buy all your friends a copy.
