If Stellar Records produces the SingItNow series, why does Greg Lazzaroni have his name listed as the admin and technical contact?
Maybe the guy who owns Stellar Records is his cousin or some other relative.
Sounds kinda strange to me.
I have listened to several MP3s from each website and they do sound identidal.
That's what I was hinting at.
On another note, I have sent three emails to "returns@@karaoke.com" and haven't gotten a response.  I do still plan on playing the Pop Spring 2005 CDG on the Vocopro player at work.  That will be the fourth email.  If I don't hear back from karaoke.com by Friday, I'll have to do something else.  Their policy says this:
"You may only exchange a defective disc for the same identical title up to 21 days after purchase."  
I'm not near the 21 days but if I dont get any responses, pretty soon I'll be close to that mark.
