So, Was the question this: Is a singer a musician?
Or this: Is the Voice a musical instrument?

Therefore, if you own a voice (a musical instrument)and can sing and this makes you a musician,

Then if you own a toilet and can take a crap in it, this has to confirm that you are definitely beyond the shadow of a doubt a plumber.

Hey I just realized I own a bunch of wrenches and tools, so I am definitely beyond the shadow of a doubt an auto mechanic, maybe an engineer, who knows there's zillions of possibilities, infiniti. I need to stop for a while and catch my breath.

If I buy Gary's sail boat then I'll be a sailor. No, I'll buy DonM's golf clubs then I'll be a pro golfer. Maybe I can drink what Dave drinks and then I will become crazy for redheads.

That's just about how stupid it is for a comment to be expressed that a vocalist who knows nothing about music other than the lyrics to a song is a musician. A vocalist who fits into this category isn't a pimple on a musician's A$$. HA ha ha ha ha ha ha ha ha!

Now this is the final word and settles the matter. So, why don't you shut this down Nigel?
