Celine Dion - Think Twice
Sarah McLachlan - I Love You
Sarah McLachlan - When She Loved Me
...that I Love You song is a heart ripper. They all are. But those are the three songs that will get me with NO problem.
Jeff Buckley's Hallelujah is another that gets me but the pure mastery of that song often overwhelms the sadness in me.
The girls singing usually make me quicker to tears/mist. Of all of them, Think Twice gets the lifetime break-me-apart award, but I Love You is probably the best song of the three (the Jeff Buckley song is in another league). Just very powerful for me and in the right/wrong state those are the songs that can take me down a peg for sure. Without exception, they of course evoke feelings and memories related to me leaving some girl, or, getting dumped that one time that was worse that like 20 breakups combined because the girl did just about everything horrible you can imagine and I loved her.
