Hi Lauraine,
It's nice to hear your voice again. We are being a little silly tonight with our big grins. Karaoke IS for everyone and I hear all kinds of singers from one extreme to the other. The "ouch singer" to the "international rock star" but mostly rank amateurs.
If someone here has aspirations to starting a singing career you need to learn from professional musicians. First, you may want to have some professional voice lessons. Second, you need to learn how to sing and work with live musicians instead of watching lyrics and a bouncing ball. There are many many many forums to go to that focus on these two issues. In addition, there are forums to learn recording and how to apply your instruments and vocals to recording.
Forums for recording is where you will find professional musicians and studio owners (small and large) where you can post your mp3 for sharing your original material and copyrighted songs.
Professional musicians are simply not interested in karaoke. In the past, we used to go out to watch live bands before karaoke came to town. Now, karaoke is often used for local entertainment to keep the costs down and to let ameteur singers in on the action just for fun!
