the clip from U2.com sounds much better than the clip we've heard. I think people should probably wait to hear a full/proper version before trashing it or loving it (mostly trashing it it seems).
perfectly fine to dislike it, of course, but i think it's a bit premature to crucify it without either 1- having been there or 2- hearing it in a proper form.
Don't think you need to hear it in any better quality to judge that the Tutu samples and a wishy-washy intro replacing the best part of the song are not an improvement.
