Yes this is a very cool soothing song......But i wouldnt have called it depression. I actually have a song on my page called "Depression" You should check it out. Not to be a wise crack or anything but my Depression sounds a little bit more depressing ;)
I wouldn't exactly call this "Not Hip Hop" -- it doesn't really seem abstract enough for it -- but this is still pretty good. The synths are great. But maybe try making the ending a little less abrupt? I was getting into it and it seemed like the song just stopped outta nowhere.
