Short answer: none
Long answer: none. But read on for details. If you want.
I wouldn’t consider anything I listen to a “guilty pleasure.” I’m pretty open about what I do and do not like, and I’m not stubborn about it either. Everything I listen to is either something I genuinely and unashamedly enjoy, or a part of an album that I don’t want to exclude since I hate having incomplete albums in my library.
However, since I’m at least expected to post a song, I’ll include something that other people might consider a guilty pleasure. I wouldn’t though.
The featured image is from Persona 4 The Golden Animation. Which is not a guilty pleasure. Or a pleasure.
