I love Renaissance music - sang a lot of madrigals in high school and college, and one of my HS classmates still plays viola da gamba professionally. It never occurred to me to put it in my iPod for water running! Most of what I have in the 90-105 bpm range is either hip-hop or bluegrass, which makes for a very wacky playlist. Some Pretorius would be just the thing to make it totally insane. 
Indy, that sounds like a fun class. I hear you on two-a-days - even when time isn't an issue, motivation can be. Heck, even a lot of the pros take an annual break from running. That's kind of where I am with cycling right now - I'm just crossing my fingers that when I'm back in hill country my back will be healed up enough to ride the hills.
I did 20 today for the first time this cycle, and it almost feels better than the first time I ever ran 20. I'm too gun-shy to count on anything at all right now, but every step forward is a step forward. I saw a bald eagle and a swallow-tailed kite riding the wind - it was a beautiful day for running, sunny, dry, not too windy, and temperature in the high 50s - and I did the last couple of miles with a huge grin on my face. Yay.
