Site on insomnia needs logo: $200 prize

I am looking for a logo for a Sleep Optimization Program offered on http://www.sleeptracks.com. The logo will be the starting point of the redesign of the whole website -- so get creative! What the logo/icon should convey: peaceful sleep...

SleepTracks

Tagline:
Restores Your Sleep Withoug Drugs

Desired Color Scheme:
need to stand out from blue background, and another version from white background

Desired Style:
simple, striking, compact, web 2.0

Accepted File Formats:
Standard Web Formats (.jpg, .gif or .png); Layered Formats

- site name: SleepTracks in one word. No need to put the .com

- include the tagline: Restores Your Sleep Without Drugs

- What the logo/icon should convey: peaceful sleep.

- I would also need to be able to append "2.0" to the logo eventually, because a second version of the product is in the works.

- the site is geared toward people who suffer from insomnia. A majority of women.

- main color of the site will be blue. I would need a version of the logo to stand out from a blue background, and another to stand out from a white background.

- I would like something simple and clean, yet striking, compact and crisp.

- You can try with some web 2.0 style reflection...

- In SleepTracks, "tracks" refer to audio tracks

- No serif or curly or handwriting fonts, please. I prefer cleaner, simpler fonts with a strong visual impact.

- Don't use musical notes. The problem is that it conveys the impression that the product consists of musical tracks, but it's not: the audio tracks are not "musical". They use a technology called brainwave entrainment (rhytmic pulses) and various background sounds to achieve to guide the brain into sleep. 

Thanks for playing!
