in my opinion:
titles that are just awesome: Two Planets Approach the Roche Limit, The Star Conquering Traveler, The Raging Lion Roars, The World to Win, Faded Dream of a Psychomeddler, Settling a Score ~ Atone for One's Misdeeds!, Supreme Ruler's Coronation - OVERLORD, probably a whole bunch more but i'm gonna end there
titles that inherit their awesomeness from something else: The Wastes Where Life Began, "Mistilteinn, Tree Crown without a Ruler"
titles that are nice in some other way: From Those Who Departed for Space, I'm a Hungry Pink Puffball!, Soaring Determination: No Night is Eternal (also partially overlaps with the above category)
titles that i pay more attention to than the song they come from: Please Don't Inhale the Cinema Patrons
a nice title for a not-so-pleasant song: Eternal Echo of the Thrilling Tour-our-our
unofficial titles that i prefer over the official ones: Moonstruck Blossom, Looming Darkness, Fly! Kirby of the Stars, Swole Dedede Scuffle
edit: yay, post went through!
