Soma 2.10.0 is ready:
http://dawoodfall.net/slackbuilds/noversion/soma
Changes:
Updated radio station URLs and removed some 404s.
Changed the dialog theme system to how it was before, so that you won't find ~/.soma filling up with different versions. Default is ~/.soma/dialogrc.
Added a greenrc dialog theme.
Things I can't yet fix:
Dialog title is in white no matter which theme you use. There doesn't seem to be a setting for that, or I couldn't find one yet anyway.
