yeah, it is more about moods and overall atmospheres than songs with singing shiny choruses etc.
actually, the first oceanic spin i had was after two or three beers, with headphones at 3 am. i sank in a kind of slumberish mood half through the album, but when the opening riff in hym started, suddenly i was like "holy shit" and wide awake, still laying on the floor.
i believe that all the people that don't get isis hate all this hype aroud them lately, but my personal opinion is that they deserve more audience, cos they simply are different. and good.
