I have 12 bp's at the moment and I am very involved with each of them. I pick them up and hold them each for about 20-30 minutes every day; of course excluding days of their shed cycle and the days after feeding. They all each have their own personalities, and we may possibly never really know if it REALLY bothers them. I'm sure they don't like it as much as we think they do, they aren't loving like a bird or a dog, they don't have that sense or instict. They are probably like "whoa, hey wait! I was sleeping! Arrgghh dang it I hate this, Oh well, oooh whats over here??" when we take them out of their cage. They aren't made to even know what a human is, except maybe a threat. But that is why handling them probably shows them that we are not a threat but more of probably a nuisance, lol.

And about music, Jeanne is right, they can't hear anything, only feel the vibrations. As long as the music isn't too loud, or there isn't alot of bass to make the bp's cage vibrate, it should be fine. Otherwise, that vibration would probably really end up stressing them out.
