“A Bad Dream” by Keane from their album _Under the Iron Sea_.
Just downloaded this after hearing it on “KCRW”:http://www.kcrw.com. This station is a model for how things should be done: Complete playlists are available listing songs up through the very most recent one played. What I do when I hear something I must have (which is usually while driving) is send a text message to my email address, which arrives time-stamped. The message is then a reminder to look up the song and add it to my “songs to get” textfile, or to just get it right away.
Is the rest of the album any good?
