I need help finding a song from a youtube video about bleach the anime?

ok heres everything i know: it as from a bleach manga video, the chapter was 353 titled the ash, this video was taken down idk whn but i know that either it was taken down or the user got banned or something, i want to know the song that was playing during the video,there was an entrance song nd the main song. i want to know the main song, it was sorta nice an peaceful/sad, not really lyrics and a woman kinda sang the tune or hummed it or something. it sounded like an ost from a anime but i cant find which one its from and the videos not even up anymoe so that doesnt help either. im basically doing this all from memory and i need as much help as possible
