Mayyyyyybe John Gregory Betancourt's The Dawn of Amber, set in Roger Zelazny's Amber multiverse.
A CD you own that no one on your friends list does:

Sadly, I can't claim Vatic[A.N.]'s Infocalypse, because tugrik has that.
A DVD/VHS tape you own that no one on your friends list does:
A recording of a video segment of the old PBS show Videolog, where they visited my tiny home town. Err, no wait, my mom has that.
Umm, I have an old DVD of an anime called A Wind Called Amnesia.
A place you've been that no one on your friends list has been:
Up a small cavity inside the underground Corkscrew mine in Death Valley, collecting Colemanite.
