Sometimes you have to overlook the fact that someone came late to the party and be glad they showed up at all. That's how we're feeling about Mumford & Sons: Sigh No More ($5). Released earlier this year, this album of awesomeness needs to find its way to your iPod last week. This folk rock band from merry old England brings some serious goodness on "Little Lion Man," "Winter Winds," "The Cave," and "Roll Away Your Stone." Warning - you may be inspired to pick up a banjo.
