"Who wants to live forever" ?
Mood music is highly group dependent. My last few experiences with it were very poor, mostly due to volume. A couple were public events using Syrinscape, the others were home GMs just picking CDs they liked. (At least at home we can work together easily so everyone can hear.)
I'd ask your fellow players if they want mood music and (if yes) what they'd like. If you have to pick, I'd suggest selections from an instrumental adventure movie soundtrack like Indiana Jones. Regardless of the choice, play it quietly so people can hear each other. (Again, group dependent.)
I've got a friend who really likes Lord of the Rings' soundtrack for that kinda thing.
I suspect it takes a lot of work from the DM to customize it enough to match moods. Or a very scripted campaign. I could see doing like a suggested track per scenario, but I wouldn't want to have to do enough music to fill an entire playthrough.
Midnight Syndicate Has several Gothic themed CDs that might be appropriate for Wrath. I used their D&D soundtrack for Runelords.
Two Steps From Hell is a good choice, I feel.
I'd find the OST of Dragon Age: Origins very fitting - both as music, and thematically.
