i recently found a great way to use my ipod as a meditation tool. i was hunting to buy a wave machine (one of those boxes that can emulate waves, rain, waterfalls and the like) to use whilst meditating and snoozing. instead, simply download free samples from freesound, and add them to your ipod under, say, a new genre, meditation. then choose the “repeat: one” option, set your dock speakers or headphones on a low volume, select your desired track, and ohmmmmmm….
searching for tags like buddhism, meditation, babbling, rainstorm, etc will yield excellent results.
