There's so many good openings out there! But only one has my heart and that is Rain by SID (Fullmetal Alchemist: Brotherhood - OP 5). (It's above so you can read the rest of the chapter as you listen).

While the opening's montage is not the most beautiful of all openings, it does a nice job recapping at the same time preparing the viewer for the final episodes of FMAB. The transitions between scenes fit well with the song and the song itself is just calming to listen to. Such a great opening for a wonderful anime.

And both FMA and FMAB are on Netflix!
