I actually really like the new OP and ED, certainly more than the old ones (yeah, definitely not a Visual Kei fan). It is a little shouty, but the full versions of the songs are better and do really fit in with the feel of the show (though I still prefer the movie themes, Red Hot Chili Peppers and Suga Shikao).
Rolling Star, definitely the best Bleach OP so far. I kept rewatching it as well (both the OP animation and the music video), and made me excited about Bleach for the first time since the start of the fillers. And I just love Yui.
The one that probably made my ears bleed was the first InuYasha OP *shudders* Maybe not extreme, but horrid to listen to.
