The tune of the final map theme actually shows up in a lot of places, including the opening theme, Heritors of Arcadia, What Lies at the End (Alm Map 2), Revelations, The Afterglow Fades, Reminiscences (Mila's Turnwheel) and Sea Winds and Travelers (theme of some harbors). There might even be some that I missed. Anyway, you get my point.
I actually really liked Lost In Thoughts All Alone, and the fact that it showed up a lot.
