I want to know the answer to the following question:
What do the initials EP stand for?
All the background I'm provided with is that "The 45 rpm discs also came in a variety known as extended play (EP), which achieved up to 10–15 minutes play at the expense of attenuating (and possibly compressing) the sound to reduce the width required by the groove.". Is that enough to answer the question?
Answer: yes
