Hawaiian music makes me very happy. I purchased a download of some Hawaiian group whose name I can't pronounce that sings in the language. I can't understand a word, but it cheers me up and calms me. To sleep, I use the ocean setting on a little "sleep machine" my husband bought me to put under my pillow. There are several other options (heart beat, babbling brook, and something else) but it's the sound of the waves crashing up against the shore and back out again, that I'm in love with.
