I think they are. I bought the album and at first my locker had only a few of the songs marked as playable, a few minutes later, more were playable, and after maybe 5 minutes they were all playable. To me, the best explanation for this behavior was that it was taking some time for Amazon to copy all my purchased songs over to my locker.

ps: I'm not a big Lady Gaga fan, but for 99 cents I figured I'd give it a whirl.
