It's interesting that the songs Carrie selects for the closing number on her album always seem musically different from the album as a whole. All of them also seem to be themes that express sentiments that are important to her - a closing message to listeners that reveal something of her outlook on life. The two that she co-wrote contain autobiographical elements - IAICA obviously so, and PO, I think, more subtly so, in that I see it as her discussion of the challenges she faces in striving to improve and fulfill her goals. The other two can be interpreted as spiritual songs, but are also non-specific, in that they leave listeners free to see the message in the light to their own thoughts and reactions.
WAY is interesting, in that Carrie says that Mutt Lange sent the song to her, apparently thinking it would be well suited to her. Lange is a Sant Mat Hindu, and two of the main tenets of that faith are the soul's inner search to understand God, and the universality of faith, transcending religious divisions. The lyrics of the song, addressing the question "Who Are You?" fit the first principle very well - and the fact that he sent the song to a Christian (and fellow vegetarian) is also consistent with the second principle. Carrie says in her video talk on the song that when she first heard it, her immediate reaction was to think of it in terms of a lover, and she saw the spiritual meaning secondly, after discussing the song. She feels that its power lies in being able to be interpreted by listeners on different levels and applied to what they see as important - but for her, the faith interpretation has become the most important.
I think the song works well, with its insistent drum beat echoing the questioning of the lyric, and the opportunity it gives the singer for a strong delivery. Nevertheless, although its grown on me, I still feel the other two songs are stronger. I can understand the votes that have gone to WAY, but I'm still sticking to the ones I mentioned in another post as my top seven.
So, for me, we're back to the two that tied in the last round - and as I said there, I'm going for BA as the more dramatic and more vocally varied.
