Each of the character has only one song that is my favorite.
Ed: Asu he no Basho
Al: Ano Yume no Mukou He (I almost dozed oFf when I first heard this song. But the more I listen to, the more I love it)
Roy: shounen yo shinjiru nakama yo
Maes: Papa to ashoubo (this song makes me think about my papa and the bond between me and him)
Winry: Boy friends
