I don't normally listen to them or like their music either - but I can still recognize objectively that they have talent. It's not a matter of taste, just recognition of the obvious fact that being an extremely popular artist means that you're talented, no matter what pretentious haters say about it.
Popularity !== talent.
Think of _every_ popular actor or artist. Do you think every one of them is talented? If so, it sounds like you’re basing your understanding of talent on what other people think.
