I have a cochlear implant and strongly disagree that it prevents me from enjoying music. So much so that I've taken up piano lessons again after a break of 20+ years.
I recently upgraded to the Nucleus 7 processor, but it sounds identical to my previous Nucleus 6 processor. Main benefit is that the Nucleus 7 is smaller and lighter and the batteries last longer.
Keep in mind though that cochlear implants are generally a last resort since implanting them will usually remove any residual hearing you might have left. AFAIK your ear has to be "profoundly" or totally deaf before doctors will recommend implant surgery. Preferred treatment is to augment whatever hearing you still have with hearing aids before recommending implants. In my case my left ear is almost normal up to 1500Hz so it has a hearing aid that does some frequency transposition for higher frequencies. Implant is in my right ear which was almost totally deaf.
Hope that helps.
