17. A Year and a Day
http://www.youtube.com/watch?v=SM32R91KMDc This track makes it on here almost exclusively for the music. Crafted from the Isley Brothers "Who's That Lady?" and Led Zeppelin's "When the Levee Breaks", this hyperactive disco freakout is also a MCA solo track. It is also the first track that showed MCA's then blossoming spiritual side. Stand out line: "But it's good to have turn, to be a king for a day/Or for a week, or for a year, or for a year and a day" 16. Ch-Check It Out
http://www.youtube.com/watch?v=wddY7qCn-ig The lead off single from their first new album after a six year hiatus, "Ch-Check It Out" is a classic uptempo Beasties track filled with references ranging from Klingons to Miss Piggy. With a breakdance beat and in your face horns, this was the perfect choice for the To the 5 Boroughs first single, recalling the music of their yester-years and showing everyone that they hadn't lost a step. Stand out line: "Don't test me, they can't arrest me/I'll fake right, cross-over and shoot lefty" 15. Egg Raid on Mojo
http://www.youtube.com/watch?v=KTtQ-uTf1uo Not necessarily one of their best songs but don't forget, this is a list of their most "definitive" songs. The earliest Beastie Boys track on the list, "Egg Raid" must be included because it showcases the bands early sound. It's also catchy as hell. The song tells the true story of a doorman named Mojo who one night was on the wrong side of an egg raid.
