There are certain tracks i like from all of them, but the hoenn gym leader music is one of my absolute favorite tracks in the entire franchise so hoenn gets my vote. --- Main: http://us.battle.net/wow/en/character/dark-iron/Nightshadez/advanced Primary Alt: http://us.battle.net/wow/en/character/dark-iron/Meladree/advanced
3 and 5 are tops(dem E4 and town themes), followed by Gen 4(<3 the snow route and Mt Coronet), Gen 2's trainer/wild music was bland but it was pretty memorable for back then overall(violet city and ice path are still wonderful), Gen 6 was kind of disappointing but has its gems(Box Legends, Geosange), gen 1 is a bit outclassed but still has the best gym leader music IMHO.
4 is definitely the best, I don't see where people are getting 5 from. 6 was probably the worst musically, and it's unfortunate because 6th gen is the only one where you can select battle music. --- 3DS FC: 5429-7051-5721
