Interesting topic that I haven't seen discussed here too much - music and the pwBPD.
I can't say if my wife likes happy or sad music. She's complained about sad movies being depressing or triggering for her. She's complained about certain songs being triggering for her (I assume because of associations with bad times in her life). But as to whether the music is happy or sad - IDK. But I do know she tends to like artists who have had personal troubles, committed suicide, or drug addicts. She's even said as much. Other art she tends to like paintings that are more abstract, clothes that are darker colors, and comedy that is vulgar and negative.
And related to this subject, she's never taken any interest in what I listen to. She actually has no idea except for what I was listening to the first time she came over to my house. The few times since I have listened to something at home or in the car, she will make some sort of comment within a few minutes indicating her irritation and wanting me to turn if off and pay attention to her, or want to change it to something she knows. We went on a long road trip after only being together a few months, and I brought a case of CDs as did she. After she got tired of hers, she wanted to look through mine. She looked through, in hostile fashion declared that she didn't know who any of them were except one and that would be the only one she would want to listen to. Let's not mention 75% of what was in her music case I was not familiar with, but was eager to listen to
