So you are a demon hunter so something sinister but your gear is kinda quirky with strange weapons so..

How about that?
Let's get this thread going again … okay, so fairly typical looking Dwarf I don't know much about … this'll cover it!

Night elf. And a rogue / scout. How about this one:

You look like you're down for invading a few prissy elves. ;)

I dunno, I feel like this song fits Pinchpenny.
Fits for all nightborne just replace House of Savoy and Badoglio with Thalyssra

This applies to all death knights:
Just replace life with unlife, love with hate, light with darkness and zombies with living/forsaken.

"Sweet Dreams" sung by Emily Browning, from the Sucker Punch soundtrack.

Hmm let's see... You are a shadow priest, and priests are usually seen as a healer class, but you are a DPS spec, so you're not what you first appear to be. I think that an appropriate song would be "Holy Diver" by Dio, since that song could be interpreted like "things are not always what they appear to be"

Ah, yes.

A very proud gilnean druid so a mixture of something medieval gothic and nature-like.. How about this?

I like to think this would capture a gilnean/worgen druid quite well!
Glink over here looks like a fellow who would dive nose-first into his studies, perhaps a bit too enthusiastic, both in a sinister and comedic way. So have this sneaky, sort of sinister music.

For some reason it won't let me view your character's profile page so I'll have to do with your forum picture and class info.

I usually like to imagine male night elf warriors date their service back to the war of the ancients on perhaps either side.

So a song that reflects that.. A bit sad and sinister yet still elven.

The character gave me a Gregorian vibe right away, but I had to dig around playlists for a bit...

Amnastaria has always had a fierce hatred of the dead, and a heightened clarity of purpose. This lines up pretty well imo..
