I love these... I love music without words most of the time (and most people don't consider it as a music category so it's hard to answer people's question of "what's your favorite type of music?" xD) I didn't expect to find the music of my #1 favorite anime forever in this "kind"... I wonder how you find these... is there even a name for these "background soundtracks only" music type?
omg I'm 3 years late 🗣️ I'm sorryyyy you probably have already figured out, but the versions of the songs from openings and endings that have no vocals are called "instrumental". and the ambient music that plays during the anime are called the "original soundtrack" "OST"
welcome back lol can't believe it's been that long too... I still come to hear this from time to time thank you for responding, it'll really help me find songs of this genre, even though it is still hard to find these types of songs... rip
