I played the first one on my record player but the needle wouldn't follow the grooves...and then I noticed that there wasn't any!! So I drew them in with a Sharpie, but still no results. When I got the second one in, I noticed that it too was lacking grooves...so I sent it out to a machine shop to have the grooves put in, but it still didn't work !! I think that it's some kind of "screwy" defect on your end See you soon!! Bedo
