considering I don't send cards
Just think if the boot was on the other foot and someone sold you a carver of a cover up and you find out it is off a cd...you wouldn't be very pleased if you are totally honest, I wouldn't be.
But at the end of the day the worst thing you can do is post a sound file of a record covered up on here, it will be uncovered in no time, as you found out to your cost.
