Why is it I get uncomfortable when people sing in front of me?

Whenever people sing in front of me I get extremely uncomfortable and will even almost start crying, most aren't even bad at singing I just can't listen to it it gives me the chills, goosebumps and some feelings of uneasiness.. is this some type of thing people normally have... a disorder? Phobia?
