The best tracks in the game are those rarely heard imo... not a big fan of many of the tracks in the la noscea, thanalan, and the black shroud^^ Coerthas and Mor Dhona on the other hand are really great and suited extremely well... plus some story/quest related/cutscene music is pure... awesome

Oh and before I forget there's the norg like music by the norg like town we can't access atm down in mistbeard cove o.< ... one of like the only dungeons WITH music attached to it^^ hehe
