N°1 : kinda strange to my ears i don't see the body of that song, the transition between the verses and the "choir" sounds a bit obvious, lack of SQ being a beachclip maybe
N°2 : the best one imo, great loose guitar playing, excellent singing...a killer one with no doubt
N°3 : Sexy Boots, chances are 99% for being the single, as we can all imagine the I-Tunes commercial (please no motorcycle please boys), pretty cool riff anyway not so vertigo-ish as it sounds on the clip, closer to some Discothèque meets Lady With The spinning head i think...sounds more consistent thant vertigo for a first shot
n°4 the closest to that typical 2000 sound, maybe ends better than it began, with some sort of loop/percussion at the end witch i found to be its most interesting part...
despite the sound quality issue of a mobile phone recording, Bono sounds in excellent vocal shape on all the clips...
