I've updated the Hard Rock, Las Vegas room key page to add four recent releases - "In Your Room Where Time Stands Still", "Knockin on Heaven's Door", "Sweet Dreams Are Made of This", and "The Mystic's Dream" (my favorite of the four).

Please take a look at the listings and contact me by email if you have any additions or corrections to information presented on the pages. Thanks!
