I'll definitely take a look at the covers when they come out (I'm too curious to pass that up), but I refuse to listen to any previews. I want to swallow the whole album as one piece, it'll be tastier that way.

Besides, previews can really kill a song because after you've listened to a preview many times, the full song really loses its charm - the song might still be good, but it doesn't have that lovely new feeling. This happened to me with MOON and crossroad. So I'm in for that!
