Another stupid invention we don't need...

Is the greeting cards that play music when opened. Every time I go into a card shop now I have to listen to some idiot opening every single one of these infernal things. As if it's not going to play the song listed on the label, or they need to hear "Bad to the Bone" or "Celebration" one more time. Not to mention the fact that the unadjustable volume on these things is set at a level that would make a deaf person cup their ears.
