I had the silliest idea last week, but it's making me happy just thinking about it, so I'm going to do it:
Monday: Early Music
I started on Friday and listened to lots of Eric Whitacre. Also Debussy, Ravel, Richard Strauss, Schoenberg, Ives, and Joplin.
Since I currently have 52.4 days of music/audiobooks/who knows what else on iTunes, I'm excited to focus my listening this way.
Afterthought: Perhaps I ought to switch to Christmas music, considering the season?
