Mix CD thoughts

I'm still looking for a new job, but I'll be doing a little participation in the Holiday Wishes community. Each year, I send out mix CDs to some lucky people. So, your thoughts on what would be a good theme to work from this year?

My choices so far are:

1. Music with Rocks In--a geology related mix.
2. Blue Lantern's Light--Songs of hope.
3. The World is Always Ending--a tribute to 12/21/12.
