Yeah, iTunes App Store really and truly has a whalesong app.
"Relax to the natural, mellifluous songs of whales.
"Enjoy this collection of whale songs from Humpback to Killer whales. Listen to the whales as you drift away to sleep. Listen to the whales to put yourself at ease while you work. Listen on the train, in the car, or anywhere else.
"While you listen, don't forget to enjoy the dozens of pictures of whales included with the application visualizer.
"All sounds are fully normalized, digitally mastered, and encoded as high-bitrate MP3s. This makes the audio quality perfect on the iPhone alone, and blissful when connected to a powerful stereo.
"Relax. Enjoy the whales."
For $.99, I really just might.
