I guess, to me it is important to keep genres separated.
I'm exactly the opposite. I like the way the one here works in that respect. Just lump it all in together. Sometimes it's good to be exposed to things outside of your comfort zone. Over the years I've heard some fine songs by some very talented people that I probably wouldn't have if it had all been categorized. I mean, who listens to country music on purpose, right? 
Well, there are many (MANY!) approaches that I have seen where you have a "TIMELINE" strip with everything new that comes in, Multiple genre tagged music that would come up in the search, "The best of all genres" just to give an example.
But in my opinion, if one goes for "specific" genre it is expected that music there would be kind of inline with the genre. I doubt that many Heavy Metal fans would sit and joyfully listen to Korean love songs or an 80 year old Folk music lover would sit and listen to Gansta Rap with tears in his eyes (I might be actually right about the tears)
P.S. I can listen to anything (including Korean love songs), as long as they are good :) But I do not believe total anarchy in organizing music is a good idea.
