As someone who enjoys music from Avril, Kelly, and Hillary, I will and do cringe at myself for still having words and tunes memorized after all these years.

Beauty is in the eye of the beholder.
And if I know anything about the universe, it is that people judge one another for silly stuff all the time. I do it and chances are good that you do too, dear reader. Just maybe not about music taste.

Because this person is someone important to you, as you are dating, it’s probably wise to confront them about your feelings about their teasing.
Let that interaction inform you.

You’ve mentioned in your question that they generally like to tease and you’re “into it sometimes ‘because funny’, but not other times like this time”. This mixed response strikes me as confusing. It could possibly be confusing to your partner as well.

Maybe it would be helpful to more clearly communicate your dislike/distaste of being teased by your partner?
I really do not want to be a bummer, but if this habit of teasing is a humor and/or flirting style of your partner, could it be possible that you’re simply not compatible?

Something to consider to shield yourself from further miscommunications and sore feelings.
