I don't often read comics on the site so, I tend to not know if there is any music attached to a comic or a novel. If this was a feature that was added to the app, I'd definitely sit down and give the music a listen as I read through something, just like on the Webtoons app. I'm all for it, especially since I'm composing music for a comic.
I think it adds an extra layer to the tone of a comic for me to enjoy. Like, let's be real, it's a little unnecessary for reading, but I find it gives me some insight on to the writer's mind of like.. what music they like, what tone they wanted to go for, how they compose a song if they did so.. I look at that stuff very fondly bc it's a reflection of how much they care about the project and how much they wanna put the reader in the world they created if they choose to add music
Though I totally understand why some people would be opposed to it lol it's a good thing that you can turn the auto-play feature off, if that's not your style of reading~
