I quickly looked at the Madoka Magica's ost and it's pretty good on the whole I like it (especially "Fateful" as soon as there's a violin I validate xD). But on the contrary for the ost of welcome to the nhk I'm not too fan, it's the style a little old-fashioned that bothers me x)
w-what?!? the op Puzzle is absolute kino, and hittori bochi and that whole melancholic acoustic guitair sound just fits perfectly with the atmosphere of the show.
also, regarding madoka magica, once you watch the show im sure u will appreciate the music much more, the op and ed are fucking top tier and the flute in puella magi sis is just great. great soundtrack for a great show
