Rime, but only because EOTC ain't here. Sad!
EOTC isn't an epic... it is 2 or 3 in one ehehehehe
But of course an updated version with If Eternity Should Fail, The Red And The Black, The Book Of Souls and Empire Of The Clouds should be added.
And I stil think that Powerslave, Heaven Can Wait, Mother Russia, Afraid To Shoot Strangers, Fortunes Of War, The Unbeliever, Dream of Mirrors, Nomad, Blood Brothers, Ghost Of The Navigator, Dance of Death, No More Lies, Face In The Sand, Brighter Than a Thousand Suns, Longest Day, Benjamin Breeg, The Legacy, Isle of Avalon, The Talisman, Man Who Would Be King, When The Wild Wind Blows are epic songs too. Now You may not like some of these songs (I don't like a Handfull of them) but nonetheless I think they fit the definition quite nicely
