Not enough mashups of these two great songs, as far as I can tell. And they do kinda fit well together-

This Is War (vocals) by 30 Seconds To Mars:

Welcome Home (music) by Coheed and Cambria:

This Is War's vocals start at 0:28, and you should play it when Welcome Home gets at 1:03

This be how it making me feel:
