Ray Bradbury was fond of the sentiment above, that you shouldn’t feel ashamed or inadequate because of the things you enjoyed. The set of cultural memes and art you like are a fingerprint of your personal aesthetic, probably as unique as you yourself. There are far better and more worthy worries out there.
That isn’t to say we don’t grow and learn, and trying out new things is part of that exploration. But the taste judges don’t deserve space in your head to demean what you like. No guilty pleasures.
