Interesting idea for a wishlist item, though. Time/Date/Day-based wendys.

Imagine...

- Always have it filter out certain songs between 8-9am and 5-6pm on weekdays, because you have the carpool in the car with you.

- Rev's suggestion of holiday tracks.

- "wake-up" music in the mornings, "cool-down" music in the evenings.

- All really-quiet tracks after 10pm.

Etc...
