Throughout my years of gaming (and movie watching), I've always enjoyed the music that doesn't get a lot of attention. Usually the music is just the background while you play or watch, so a lot of people don't pay attention to it.
In the last few years, I started paying more attention to movie and game music. With the new consoles and more powerful computers, they've been able to make much stronger music, though I do enjoy some MIDI and 8-bit beeps and boops, too. Fortunately, it has also been brought into the mainstream with  shows like Videos Games Live.
I was able to hear the WoW music more in-depth after Syrana bought the Collector's Edition of WotLK. We actually used to use that CD when we fell asleep. We also now have the original soundtrack and the Burning Crusade soundtrack, plus she plans on getting the Cataclysm CE once she has time to play again. I really enjoy a few songs from the soundtracks.
Here are a few of my favorite songs from the soundtracks. (You can listen to them in the player below.)
- My favorite is the one on the Burning Crusade soundtrack named “The Sin'dorei” though you may know it as the music used in Eversong Woods. It's very peaceful, but with some dark cello parts. It makes it sound like everything is wonderful, but there is a darkness just beneath the surface. Similar to the Blood Elves themselves, I guess.
- Another one I enjoy from BC is called “Azuremyst Isle.” It's not hard to tell where that one is from. This one has sort of a Native American feel to it with the wind instruments. It's very calming and peaceful.
- I also enjoy the music from the WotLK cinematic, which they call “Arthas, My Son.” It's very dark and brooding and it gave me chills while watching the cinematic and hearing that beautiful voice come in.
- Two others that I enjoy from WotLK are the songs from both Howling Fjord and Grizzly Hills. The first one having the same name as the zone, “Howling Fjord” and the second one named “Totems of the Grizzlemaw“
My favorite is the music in Grizzly Hills. It’s very peaceful to me.
On youtube there’s a channel something like wowmusicguru that has a lot of them.
If you like the Wratch cinematic intro, this song [Invincible] ramps it up a notch.

Oh – and #1 is, I believe, the background of Lament of the Highborne as well – without the cello.
