U forgot Hallowed Tower in DPLavender Tower/Town, Mt. Pyre
Probably "Spacial Cliffs" music from Pokémon Mystery Dungeon: Explorers of Sky...
If you are including remixes, then Pokeremixstudio's first remix of the Primal Dialga Theme is just awesome...
Who doesn't love that song! at this point I think they should put it in a game. (Well if they could get the rights from WB.)None of the music sticks in my mind as a favourite
The theme song from the first Pokemon TV show can't be beaten though! :) (Sorry, off-topic, I know)
