Missed last week's Lost and want to be caught up through the medium of music? Then thank Previously On Lost, whose entire schtick is to put up weekly songs on their MySpace page bringing fans up to date with what they may missed that Thursday. You may mock, but one listen to "We're Goin' Home" and you'll be humming "We are the Oceanic Six" to yourself for hours afterwards. Previously On Lost [MySpace.com]
