Is listening to gaming music OK?

I have quit gaming for about a month now, and I feel really happy with life. However, there is still this one issue that's bothering me: Is it OK to listen to video game music? I have tons of songs from video game soundtracks on my phone, which I listen to periodically. This hasn't made me any closer to a relapse, but it kind of causes music to get stuck in my head, which in turn makes me think about games when I could think about something else. Is it still fine anyway?
