If you can't wait until May to get your hands on the complete album, it will be available digitally April 15th. That being just as far away for all practical purposes, give the following two a try to give you the flavor. Sweetest Day has got a guitar line just under the surface that instantly reminded me of U2's One and along with the 7th track, Love, has the most organic texture to it. Satellite has got an electro-geekish pop to it that makes you want to root for the guy with the pocket protector.
