You seem to be wanting a 'private company' host for which you pay money.

Many musos in my experience, use the free publicly available systems such as Myspace, Facebook, Youtube, and such places like many free hosters that have since ceased etc.

As far as the first case, since very few have responded so far, it seems likely that very few people have any useful relevant information about such as GoDaddy, Yahoo, AT&T, etc for you, sorry.
