a few years ago around like 2022 my friend told me that he found this community of people that would talk to each other through apple music. they would name the playlists the name of the person they were talking to and they would write their messages in the playlist descriptions. it was very odd and when i found my friend’s account he was using it to do roleplays with people ? does anyone know the communities i’m talking about? i can’t find any trace of them online so i’m wondering how this guy even found his way into that corner of the internet.
