If you thought that some of the difficulty levels in Rock Band were a tad outrageous on all peripherals involved, or if you thought they were banial at best, you will either be disgusted or pleased with the information that IGN discovered about the upcoming sequel to the music simulation hit.All 84 tracks have been listed in order of the hardest to the easiest for bass, drums, guitar and vocals. Since each list is a bit more comprehensive that the space here will allow, I will only post the chart for guitar. However, would it surprise you to know that Bob Dylan’s “Tangled Up in Blue” will be the hardest vocally? Seriously, it is hard enough to sing along to Dylan on the radio let alone for points in a game. Bass and Drum wise, hardest song will be Dream Theater’s “Panic Attack”, the Band as whole will find that Judas Priest’s “Painkiller” to be the most challenging.Anyway, without further ado, here is the list for Guitar from easiest to hardest:84    Survivor - “Eye of the Tiger”83    Modest Mouse - “Float On”82    Smashing Pumpkins - “Today”81    Duran Duran - “Hungry Like the Wolf”80    Squeeze - “Cool for Cats”79    L7 - “Pretend We’re Dead”78    Lit - “My Own Worst Enemy”77    Linkin Park - “One Step Closer”76    The Go-Gos - “We Got the Beat”75    Paramore - “That’s What You Get”74    Bikini Kill - “Rebel Girl”73    Beastie Boys - “So Whatcha Want”72    Nirvana - “Drain You”71    The Donnas - “New Kid in School”70    Cheap Trick - “Hello There”69    Presidents of the USA - “Lump”68    The Guess Who - “American Woman”67    Social Distortion - “I Was Wrong”66    Panic at the Disco - “Nine in the Afternoon”65    Jane’s Addiction - “Mountain Song”64    Alice in Chains - “Man in the Box”63    Lucana Coil - “Our Truth”62    Billy Idol - “White Wedding Pt. 1″61    Beck - “E-Pro”60    Talking Heads - “Psycho Killer”59    Norman Greenbaum - “Spirit in the Sky”58    The Muffs - “Kids in America”57    Dinosaur Jr. - “Feel the Pain”56    Red Hot Chili Peppers - “Give it Away”55    Speck - “Conventional Lover”54    The Main Drag - “A Jagged Gorgeous Winter”53    Joan Jett - “Bad Reputation”52    Elvis Costello - “Pump It Up”51    Alanis Morissette - “You Oughta Know”50    Fleetwood Mac - “Go Your Own Way”49    The Libyans - “Welcome to the Neighborhood”48    Interpol - “PDA”47    Bad Company - “Shooting Star”46    Bon Jovi - “Livin’ on a Prayer”45    Lush - “De-luxe”44    AFI - “Girls Not Grey”43    Blondie - “One Way or Another”42    Bob Dylan - “Tangled Up in Blue”41    The Replacements - “Alex Chilton”40    Pearl Jam - “Alive”39    Jimmy Eat World - “The Middle”38    Jethro Tull - “Aqualung”37    The Sterns - “Supreme Girl”36    Disturbed - “Down with the Sickness”35    Rise Against - “Give it All”34    Mighty Mighty Bosstones - “Where’d You Go”33    The Offspring - “Come Out & Play (Keep ‘em Separated)”32    Foo Fighters - “Everlong”31    The Who - “Pinball Wizard”30    That Handsome Devil - “Rob the Prez-O-Dent”29    Rage Against the Machine - “Testify”28    Devo - “Uncontrollable Urge”27  ...
