I liek the Wi-Fi music, Old Chateau at night to freak me out, ^.^ and my absolute favorite music is at the Lakes. Isn't the Lake music beautiful? I listen to it over and over and over...and it's kewl when you are fighting the Legendary Trio, and Cynthia too.
And, unrelated, kinda...I LOVE the Rival Battle song when fighting Gary on FireRed/LeafGreen!!!!~
