Ehh...
I thought it was boring. Nothing really happens. People have been using "soothing" as an excuse for boring for ages, but I don't buy into that crap. People generally don't listen to music to go to sleep, they listen to it to be interested in it, and interested is the exact opposite of how I feel towards this song. I don't suppose it's much worse than all the crap I've heard on this site though. At least it's not electronic, meaning, I can listen to it without my ears feeling like they're bleeding from talentless people creating electronic techno loops in Fruity Loops, so you have that going for you.
You can call some elevator companies though, I'm sure they'll be more than willing to please their customers while they ride with your music.
