LWR, Sad Serenade (but this leak has so worst quality, i stopped after 10 sec....), and i read, that Stars Dance leaked too, but the point, these all make some buzz around the album, especially LWR, which is very nice, beautiful song after 5-10 listening
Hollywood Records definitely would not purposefully leak music. Maybe out of negligence knowing their messiness, but it was def an insider or someone who got a hold of advanced songs.
