Here are my impressions of the clips, after almost a day of listening:
No Line - I really like this. Lyrics sound good, although Bono's voice is kinda... off... to me. Instrumentation is excellent. I'm really excited for this one.
Magnificent - The title says it all. This clip is really, really good. By far my favourite.
Unknown Caller - I love the mood set. Very Passengers-esque. I really want to hear the rest of it; I have a feeling it will be a masterpiece.
Moment of Surrender - Same as Unknown Caller. Very beautiful mood created, and Edge's falsettos are great. I really want to hear the rest.
Crazy Tonight - Pleasantly surprised. Kinda sounds like a better version of ATYCLB. But the lyrics that we can hear are kinda iffy (although better than they could have been).
Stand Up - Again, pleasantly surprised. Lyrics seem decent, although I'm not sure about the little old lady part. We'll see on this.
Fez-Being Born - All I know is that I really,
really want to hear more.
White as Snow -
I really don't like this one. Instrumentation is intriguing, but I'm not sure about Bono's voice... and I really, really don't like the lyrics that I hear.
Breathe - Wow... I'm really intrigued by this. Instrumentation is absolutely amazing. Bono's voice sounds awesome, but his lyrics are just bizarre (not a bad thing, per se). It will be interesting to hear all of the verses in context with the chorus, which I really liked in the beach clip.
Cedars - Similar to White as Snow, except, where I really dislike WAS's lyrics, these just piss me off. Again... we'll see.
Overall, I would say that these clips sound instrumentally stunning. In particular, I haven't heard Larry sound this amazing in a long, long time (perhaps ever). But Bono's kind of scaring me. I'm trying not to judge him yet, because how a lyric sounds can really change when put back in context. But lyrics are a huge thing that I listen to in music, and I'm struggling to hear much of anything that impresses me on here. Yet.
