Ok, OK, got my lazy-fat-*** to wizard rss site, downloaded the extension. For the life of me, I can't (or don't know how to) add mp3car RSS. it claims that mp3car is invalid url. went back, read all the FAQs, no dice, the FAQs are geared towards someone who already know how to add channels but looking for trouble shootings.
OK, homework done

, now, how to add mp3car as channel?
