I like what I'm hearing in these clips very much, but I'm not going to form any real opinions until I hear the full album. 30 second clips can be misleading, so while I am excited by what I hear for the most part, I am trying to remain cautious.
The one thing I will say is that these clips have only reenforced my opinions of Lillywhite and Eno/Lanois. I don't think Lillywhite is a bad producer, I just think that while he worked well as their main producer in the early days, U2 have long since gotten to a level of creative and artistic talent that surpasses that of Lillywhite, and I think, as evidenced by Bomb, that Lillywhite as the main producer for U2 at this point holds them back creatively. He just doesn't know what to do artistically with with the stuff U2 comes up with. He's bound to play it safe more often than he is to push the envelope. Eno/Lanois - especially Eno - on the other hand, know how to coax the very best out of U2, they know how to push the band when the band needs a push, they know to get everything out of the band that the band has to give. Eno/Lanois are on that level of creativity and artistry(to be honest, they're probably on an even higher level, especially Eno), and they just simply know how to push U2 out of their safe zone. The two of them are just artists in a way that I think Lillywhite isn't, and their importance to U2's career cannot ever be understated.
Anyway, this does remind me of when u2.com was 'hacked' in its infancy back in the fall of 2000 and we got to hear the 30 second clips from ATYCLB for the first time. I played those things to death. If I remember correctly, the 30 second clip for Beautiful Day was the outro(what you don't have, you don't need it now, etc).
magnificant 
I'll be coming back and listening often. I'm definitely intrigued by the new album. 
song if I had heard it for the first time on the album, but I love it anyway. Can't wait for the Grammy performance too.
