Phil Torrone notes that he is seeing iTunes 4.9 hitting his RSS feed. I am too. Note to you Apple engineers: you are using the Bittorrent feed and seem to not be getting anywhere. Try using the direct MP3 feed and you’ll have better results.
Update: Cool, TUAW picked up on this. Just to clarify, it’s not that iTunes is gakking on the feed, it’s that it downloads the feed and then never requests the torrent files. I assume that is because it doesn’t recognize them as needing downloading, not being audio files and all.
