I love listening to Epic Music.
My favorites are Strength of a Thousand Men, et al from Two Steps from Hell.
There's also Hymn of the Apocalypse from Jo Blankenburg
Some of the WoW background music is great, too.
and
to name a few~
I usually just let it go on autoplay and treat it as background music,(I can't truly listen to it while reading) then when it becomes too distracting or if it becomes a different genre altogether, I stop.
Anime opening songs are awesome, too!!
Bleach, Naruto, Naruto Shippuden, Reborn, etc, love 'em.
Neverfire7 great taste. I like the first one a lot.
