Is there a web site where I can listen to poem being read?

I couldn't find any websites but will podcasts do? These are audio files you can download from the internet or using software such as iTunes. They are also associated with an RSS feed (http://en.wikipedia.org/wiki/RSS_%28file_format%29) which allows you to subscribe to the podcast to see when new audio is released.
