At first I felt like a total idiot for unknowingly buying the (basically) same track twice when I was on my iTunes binge of DW music, but then something clicked and the resulting moment of "oooooo...cool!" was well worth the extra $.99.

(Any interest in getting a copy of some tracks? I have something like 20 of my favorites, and could even throw in some XMFC for the one theme's entertaining similarities to 11's "I Am the Doctor.")
