Hi Harry,
To tell you the truth, I have no idea what's happening in 'the genre'. I think that there are so many sub-genres splitting off of other sub-genres, I have no idea what anything's called. I actually just got into Ableton myself (I'm 25) so I'm still learning what most of this stuff is all about (theory and everything). I actually grew up listening to quite a bit of the genres you listed (except R and B).
Finding good electronic music is tough to do. I've never had luck with internet radio, usually just seeking out music directly on Bandcamp or Grooveshark. I'd reccommend checking out Kiln
http://kilnaudio.com/, and even the soundtrack to Machinarium
http://bandcampsbest.com/2011/03/13/tom ... oundtrack/. Based on your style, I think you'd dig this music. You'll probably get a few ideas in the process.
Ableton's an absolutely awesome program. It really doesn't pigeonhole you into a certain genre, with all the different sounds it offers. It's just a matter of how accessible you want your music to sound, how far you're willing to go into one direction or another. I'm still learning myself, as are many in this forum. If you're looking for more technical info about electronic music, I'd highly reccommend reading Tarekith's guides

Good luck and have fun!
