I'm sure I'm a little "late to the party" on this one, but I just found out about something called Rockabye Baby Music. Basically, it's your favorite music rearranged to "lullaby format," ranging from The Police, to Kanye West to Guns N' Roses. Though it becomes a little unnerving to adult ears after awhile, it sounds like a fun baby registry gift made for cool moms everywhere, and good way to get yourself in touch with your soon to be "mama side," without having to throw out all your pre-baby preferences.
