In this case, I suppose, you could use я вам буду нравится, still it requires some clarification, i.e. моя музыка будет вам нравится, but if you use я вам понравлюсь, it would achieve the same result and will be more clear.

I don't remember whether I'd ever actually heard the construction я вам буду нравится in my life.
