I was downloading an app that was unrelated to music, and saw this dialog:

I did not realize this was part of the new User Agreement from Microsoft, and I unchecked the box so as not to give the app access to my music history.
Now that I know it was unrelated to the app, but more to Zune, I would like to enable this setting.
How can I find it?
Settings(system)->->email+accounts->Windows Live, orSettings(applications)->music+videos(perhaps Zune account settings)? – row1♦ Oct 21 '12 at 11:31
