You can also check out artist like David Parsons, he (for example) makes really nice meditative music with quality. I use it myself for getting to sleep.
Usually if you buy (or download ) a cd marked “Meditative colourful rainbow journeys” or something you hear they’re made without a “soul”.
(My mother bought a meditative cd called thunderstorm to get to sleep for €1,50. You do indeed hear a storm coming, rain falling slowly getting louder, then as you drift a sleep after about 45 minutes you hear (very loud) a sound I can only describe as the call of a female elk wanting to mate. Waking you instantly)
And I wish you luck.
