Here are three of my favorite channels on YouTube.
These two; (http://www.youtube.com/user/Niiiiiiiiiiii) and (http://www.youtube.com/user/MrSuicideSheep) are chill-step i.e. closer to dub-step, but very relaxing and dreamy.
Whilst this one; (http://www.youtube.com/user/thesoundyouneed1) (my absolute favorite) is just angelic and has Amazing remixes (http://www.youtube.com/watch?v=NDH1bGnNMjw) this one for example.
Hope you enjoy!
Also do let me know if you know any other similar one’s.
