The song remains the same

I'm listening to the new Sarah McLachlan, and while I'm used to the concept that a lot of Sarah's stuff sounds like the rest of Sarah's stuff, I am amazed to find that when I pause the music to converse with a colleague, Adia is stuck in my head. I haven't heard that song in a long time. It's not even my favorite Sarah song. Apparently, however, it is the one imprinted on my brain. Dammit.
