So now you can tweet links to iTunes? Yawn. I've never used iTunes and I never will. It was a ridiculously crappy locked down system and now it's a slightly less ridiculously crappy locked down system. If you want to tweet links to music, just stick the YouTube URL through a shortener and it'll appear in the preview pane; no iTunes, no locked down Appleness, just a link on the open web to the song you want to share. This adds nothing, helps no-one and should be ignored so it will go away.
