The sola OP is made of win. From the perspective of someone who hates American pop music, and has a decent amount of classical training, anime openings are masterful creations that shamelessly utilize a variety of compositional techniques for maximum emotional impact. (OK, catchy melodies aren't really a compositional technique.)
Too bad sola seems to be a heaping mass of cliché so far. But I'll probably keep watching, due to the high production values. The zettai ryouiki is pretty powerful too.
