Well, it's certainly nothing I'd ever listen to voluntarily. I knew you had reversed something right off the bat when I heard that noise. I don't think the reversed noise sounds very musical at all personally, and the drums really sound out of place and not well thought through. Sorry if that sounds harsh, but I really don't like this track all that much. It's pretty much the same sound for all four minutes and never really goes anywhere besides strange drum patterns. This either needs a lot of work, or you just need to scrap it and start fresh.
It doesn't really convey a relaxing mood to me, just sounds more like disorganized sounds, and I really don't like the reversed noise at all.
