Faye,
I understand your want of com/music. I have other hobbies where it's great to be able to communicate back and forth and motorcycling is no different. You might, for this question, try a forum where the riders are more experienced with the kind of technology you need, such as maybe a Goldwing site. My guess is that to do what you want and do it well will cost a few bills. The other thing is that bikes in the 'Wing class have enough bodywork so you can build in anything you want to protect/hide it. Our bikes aren't designed for that. Good luck.
