I like the idea as it would be easy to diffrentiate stles. But, I am sad to say my style/genre you probably not get much attention. With the current format I can slip my stuff in on the sly and people will listen and give a suggestion ony because my song was thrown in on the mix.
Take Pandora for example. If I choose a song by Earth, Wind and Fire every other song will be like that style of song while plugged into Pondora. I will miss out on a style/genre that I may actually end up enjoying. I am a Rock, Jazz, Fusion instrumental kind of guy, but enjoy listening to all the other stuff that gets posted here. Hopefully people genuinly enjoy my stuff as well.
