To answer your question here: we use your email to send you notifications of likes/comments/follows as well as three emails a week of trending music on wavo. Eventually this email will be personalized to you. As for why it's not clear up front - we made a conscious effort to keep the landing page as clean as possible. Ideally, our explanation should be part of the facebook connect dialog, but that's not actually possible. Probably when we add multiple signin options, we'll add more explanatory text there.
