Cover art has now been posted for most of these releases. They've added a vertical strip on the left edge of each to denote that it's a Rarities Edition and not the original album:





In addition, all are now being solicited by UMe with this description:

2010 stand-alone single disc release that contains all the bonus tracks featured on the second disc of the Deluxe Edition release of this album (ie: does NOT contain the original album, only the rarities associated with that release). Perfect for collectors who may have missed the double disc version or for those who are in search of all the great tracks that were initially exclusive to the Deluxe Edition.

The Melissa Etheridge one appears to have been cancelled and replaced by Motorhead's Ace Of Spades, so I've updated the pre-order links in Calijawn's opening post accordingly.

UMe does plan to make Rarities Editions for many, perhaps for all, of their previously issued Deluxe Editions — Bob Marley's Legend has already been scheduled for February, with more to follow.

There may be 1 or 2 worth picking up depending on price......
