Good to hear you're going bowling. But, twice in your second to last post, notice how you said "see what kind of reaction I get" and "watching her reaction."
You can't worry about her reaction.
It may be solution based, but don't think of it or do it as an experiment. Do it as an activity YOU want to do for you. You've got to go bowling for YOURSELF only. If you actually do like the RB and hip hop, you've got to like it for yourself, not as an experiment. If you truly don't like it, then quit listening to it. Whatever you're changing has to be for you, independent of how she feels about it. You don't want to start doing something, and then look over your shoulder every time more or less asking her "Well?". It will likely come across as fake and weird.
When are you going bowling, BTW?
