While I've always appreciated some music due to some amazing specific technical aspect, such as Jacob Collier's harmonies or Steve Vai's guitar skills, the records I'd take with me on a desert island tend to consist of very simple elements combined and executed just perfectly. And by "perfectly" I mean with all their imperfections and unquantifiable emotional appeal, which has very little to do with the level of technical prowess. I guess what I'm saying is that for me, taste matters more than skill in music.
