This addon was uploaded because Rossmallo on wowhead said, "I really hope that this unlocks the ability to switch our normal death noise with the one Auriaya has." I felt bad for Rossmallo, and wanted to make it into a reality for him/her via an addon, until such time as Blizzard recognizes the genius in his/her words.
This addon plays Auriaya's death sound when your character dies.
Also, the title granted by the achievement should really be "Crazy Cat Lady" for both genders. Just Sayin'.
Hugs n Stuff!
P.S. Since I lost most of my old data, I'm freshly re-rewriting one of the ones I've as-of-yet-not-released, so I might be out with something new soon™.
