My favourites are the ones that could pass for actual songs if they didn't yell "Pokémon" randomly haha. The first opening brings back all the nostalgia and stuff, and if you decide to start singing it, 4/5 people would join in. Johto Journeys was great, all happy and somewhat sounds like some 80's happy-rock or whatever. Master Quest was cool, pretty rockin'. Advanced Challenge was pretty sick, like super intense and everything. Pretty upset they didn't make a full-length of that song. Advanced Battle was equally awesome, brings back memories. XY's opening is awesome, like a combination of all the openings I mentioned earlier and the original song... However the second XY theme I'm disappointed in...
