I'll just say that the more genres there are, the more opportunities there are for combining them. For example, there are great artist combining electro/house with rock/metal. And, on the other hand, the more technology there are, the more potential there is of making good music. So, logically, the more there is, the more can be created. But is it happening? I'd say yes. Because, even not very famous, there are artist who make absolutely every kinds of music. The problem is that the most commercial music is only one style, but when it wasn't like that?
