When you record someone specifically for their voice, they have a tendency to sound uncomfortable just because there's no immediate dialogue. When I did that "interview" for instance, it was mostly just me rambling on about the ideas I had and the elements I used in the song.
Since you were cool and posted a clip of your singing, and I'd like to hear ZG singing as well, here's part of a vocal track to one of my songs.

EDIT: CSM, I watched that flash. You're a pretty good voice actor, especially considering what I was expecting.
