Grand Funk Railroad was, at best, a singles band, capable of turning a couple of crunching rockers and hooky singles out with each album. Though it may be missing a fan favorite or two -- and that could mean something concise and catchy or meandering jams like "T.N.U.C." -- this does have the overwhelming majority of their best songs, including not just hits like "We're an American Band" and "Some Kind of Wonderful," but also album tracks. Some longtime fans, like Homer Simpson, may find favorites missing, but this remains a nearly ideal summary.
