Just call your tracks whatever genre you want. SoundCloud lets you write in whatever. Then, promote your whole SoundCloud site*, and YOU tell your listeners what genre you are. Don't wait for them to search for you. Make your page easy to find.
*Best way to create a presentable SoundCloud site, imo, is to create a few sets (however you want to arrange & customize them), and click the little wheel on the right of the profile screen, next to your "Mini Update". You can set it so people see your sets when they first land on your page. I think "sets" looks nice and clean, and gets all your tracks up on the top of your page, without people having to scroll or click "next page".
