With music, I go in waves. I listen to all different kinds, but I tend to hover around a similar style for a while until I move on to something else.
Thats super cool! Not so many do. I would see, the more openminded people do, the rest doesnt. Though I have my favourite genres, I always try to listen to music from any other genre. Maybe not in waves you do, but more constantly. Sometimes its a bit of searching in genres I dont know, since I need to get to the gems in a particular genre to be able to appreciate the music. And I need to be in the mood for it, espacially when it concerns genres that are far from being my favourite. That said, its sooo nice to be able to be openminded enough to take on any music style.
