MUSIC RESEARCH PROJECT

I have a hobby of picking a genre of music and researching it intensely. I find the roots of the music, it's sounds, the artists that created it, and just about everything else there is to know about it. At the end of it I make a massive playlist of the music and post it on my playlist.com account. I'm having trouble picking which genre to research next. Any ideas? I'll be sure to give you credit.
