Pokémon Black and White Versions/Features/Changing music

Whereas in previous games, the main music track always remained the same throughout battles, in Generation V, the battle music may change with the situation. For example, when battling a Gym Leader's last Pokémon, the music changes to a remix of the main theme. The warning sound heard when a Pokémon has less than ¼ of its maximum HP remaining has been remixed into its own music. Some "rare" wild Pokémon also get their own theme. While not technically new, the seasons also change the music in certain places, though these changes are mostly changes to instrumentation, similar to how the day/night cycle could affect the music in Generation IV.
