So, I dated a guy for a while and he happened to be a musician. While we were together, he made roughly 25 songs, all of which are on my iPod.

Fast forward about a year, and I was showing one of my playlist to someone I've been seeing for \~2 months, non exclusively. One of my ex's songs came up and she thought it was a really good song, so she asked me who it was by. I told her the name, and thought that was that. A few days later, she texted me asking why I still listened to my ex's band and why I didn't tell her it was his band. Apparently she looked the band up so she could download their music herself, and saw his photos with the band and put two and two together (I don't delete photos off of my instagram, even after relationships have ended, so I assume that's how she knows what he looks like). Anyway, I told her I didn't think it was a big deal, and she said that it was obvious I wasn't over him and that maybe it was best we don't see each other anymore unless I'm willing to delete the songs. I told her that I really like his music and I don't see the need to clear out songs that I enjoy, no matter who they were written/performed by. 

Is this weird? My ex and I are still friendly, but we rarely talk, and it's been a year since we broke up. I'm over him, and that I didn't think anything of keeping his music on my iPod, since I genuinely enjoy his music (&amp; I'm friends with everyone in his band anyway, and I like to support my friends). I did delete two songs right after we broke up, because they were about me and our relationship, but I didn't see a necessity to delete the ones that had nothing to do with me. Anyway, AITA?
