A DWMV is a Doctor Who Music Video.  I've made a few in my life, but they were always matching up an existing song (eg: Pressure by Billy Joel) and cutting clips from the series.  This, on the other hand, is an original Doctor Who song (like Doctor..? by Blood Donor was, and Doctorin' The TARDIS by the Timelords wasn't...) This song is by Chameleon Circuit, and is called An Awful Lot of Running.
