It sounds to me like regular sims not in the singing profession can not have a good singing voice (other than learning the songs from other countries). Is that correct? If so, I'm disappointed with the kareoke machine featured, as I am a singer myself. It was one of my favourite things in Sims 2, they all had one, both for individuals and pairs. Also, a great friendship booster. I currently have two sims going through the music profession, one rock, the other symphonic. I take it they won't be able to sing either (certainly not so far and they're at level 9). Do they keep their singing ability if they go through the singing profession and then quit. It might be worth it just so they can sing. They'd have to quit their music careers though. Ughhh.
