Theme songs that you just love a lot and could probably listen to a lot?

For me: Pretty much any Fullmetal Alchemist Brotherhood theme song theyre just so good The first theme song in the first season of Assassination Classroom and the first theme song of the second season. The theme song to Mahou Shoujo Madoka Magica The theme song of Steins Gate The first theme song of Toradora The first theme song of Your Lie in April The theme song of Cowboy Bebop The theme song of Death Parade To name a few what are yours?
