Let me explain why.
If I would just learn seforim and not websites, I would think that married women must cover their hair and that I [a man] may not listen to them singing. But I was at the website of an "Orthodox Rabbi" today where I learned that married women DON'T have to cover their hair and that I MAY listen to women singing [even OPERA!! Why would I want to do THAT??].
He had other "brilliant" and "innovative" ideas but I will leave this for now and give him a bracha that he should do teshuva and that I SHOULD JOIN HIM!!!!
ELUL IS AROUND THE CORNER!!!!
BTW - His name is ..... psyyyyyyche:-).
