Last.fm and YouTube

To upload our video recording onto my blog it was as striaght forward as i thought it would be. In stead i had to join a website called http://www.last.fm/. This site allows up to upload your music etc. I had to become a member of the website and then try and work out how to upload music. I have also joined YouTube to see whether i would be able to upload my auido interview on that website.
