As long as they're amazing in bed, it makes no difference.
But in all seriousness though, similar music tastes would never be a requirement when looking for a prospective partner. It's something so trivial that anyone who would choose to date/not date someone based only on that is someone with issues of their own. In fact, I'd
prefer to date someone whose tastes and interests are the opposite of mine so I could broaden my horizons and learn new things through them and vice-versa. Dating someone who's basically a clone of me in terms of personality and taste would get incredibly boring very fast.
