I think I'll have to try to remember the idea of singing when needed as you did.  Your trip doesn't sound strange to me at all. I love this stuff too, but from a distance.  I would like it to last longer and also I would like it to be something I could do ten times a day, but then I'm glad its not because I think I could get consumed by it. As it stands, a few times a week use at the most is what it allows me to do.
