Topic: Radio twitter

Can someone help me?
I like twitter a lot and I want to create radio twitter, which would be
twittervision but on audio with the best messages. A raw example is
here:
http://tinyurl.com/382267 but it lacks some background music which would
be nice. I am not a programmer so if someone wants to jump in, thanks!
Radio twitter will be open source.
Thanks!
