No, it's perfectly reasonable to not like popular music. I was only responding to what I perceived to be amazement in your previous post that someone is claiming you might find a way to enjoy ABBA: I was claiming that, since a lot of people do enjoy it, it shouldn't be hard to imagine that you could find something to like one day.

Conversely, if you said you don't know how you could possibly enjoy, say, the Plastic Ono band (Yoko Ono's band), then it would be harder to suggest it's even possible (not to say that enjoying them, for anyone who does, is in any way wrong!).
