Still not enough.
The whole point is a two fold view. You shouldn't have to question what you like, but on the same coin, you shouldn't like something for the sake of following others. I listen to Green Day almost religiously, but that's because I not only like the sounds, but the messeges of the lyrics. In the end though, if someone said I had bad taste, I would shurg it off since it's not worth a fight over something trival.
So the final anwser is no, you don't have bad taste, but with that said, you/I/anyone does not have the right to say who has "good/bad taste".
Just listen and enjoy.
