I think its only embarrassing to me if i sing front of people i really dont know or people i just met. But if im with close friends id be singing all the time just to see there reactions i have a horrible singing voice lol.
I don't find it embarrassing at all to sing unless I mess up! I may be nervous to sing in front of people but not embarrassed. I karaoke all the time and I love to sing and everyone always tells me what a good job I done so that makes me feel confident enough to get back up there and sing without worry!!
I do when it's just my family.I feel like they're judging me harshly or don't want to listen to it.But I sing every sunday at church with no problems,while playing the organ.lol.
