The sarcasm is strong in this verse.
Taylor is saying that she is not going to miss him picking fights for no reason or the way she falls for it and fights back (when she should be smart enough to ignore him).
After they fight he takes some alone time to cool off and listens to some indie band that is soo cool (you’ve probably never heard of them…), which pisses Taylor off because she wants him listening to her own CDs.
