If you don't know who these guys are, you can read about them here and here.
It's not what a person says that makes you want to listen to them, but how they say it. If a person has an annoying voice, it's hard to focus on anything other than the sound. On the other hand, if you like a voice, you can listen to it talk about anything, even something like door knobs or car parts. Sometimes I can go through an entire day just hearing the sounds of different voices without really taking in what's being said. And sometimes I'll hear myself saying something to my kids for the 16,000th time and realize I might as well be saying Bladiddybla-nasalpassages.
