I know everybody uses it but iTunes sucks a hard one. Kissyman pt 8 won't download in iTunes. I get error messages in iTunes all the time and it gets old. It usually doesn't bother me that much but when it a SIGLER podcast I get a little pissed. At least there's download helper in firefox.
Scott, you should make a "download mp3 file" button on your site so people can directly download the file from you (not just play it in the browser).
