A Diglett-sized addon that plays Pokemon music during pet battles (wild encounter themes when engaging wild pets, trainer battle themes when battling NPCs or other players).
Currently includes music from Red/Blue, Gold/Silver/Crystal (Johto daytime), Ruby/Sapphire/Emerald, FireRed/LeafGreen, Diamond/Pearl, and HeartGold/SoulSilver (Johto daytime), with the ability to add more if it floats your boat. By default, it uses Red/Blue's themes only, but you can set it to use another generation's music (or select one of them at random for each battle).
Please note that I Choose You! has no in-game configuration - if you want to change how it behaves, open config.lua inside the addon's folder with any text editor and modify the options listed there.
Changelog:
v1.1 - horrendously late/small update to correct a serious bug where battle loops would not play if music was disabled and alwaysOn was. Sorry about that.
v1.0 - initial release.
