The order of the tracks in this playlist may seem confusing as, unfortunately, a lot of them are mislabeled (for example, the track named "Dragon God" in reality is the theme of Armor Spider). The order I went by in this playlist is what I perceive to be the order in which a player following natural progression in the game will hear them: first the theme of the boss of world 1, then 2, then 3, then 5 (as its difficulty is generally perceived to be lower than world 4) and then, finally, world 4 before the cycle repeats with the tracks from the next stages of each area. This order is interrupted by tracks not assigned to bosses like "The Nexus", which are still placed in order that an average player would hear them in.
