Why do girls say i stink at singing but guys say i am amazing?

Well, girls are catty you've gotta realize. A lot of them might wish they had a better singing voice, and even if they can't hit a note, they might listen to the way another girl sings, and decide that she makes the notes too fancy or something. They decide, just because the girl shakes her voice too much, or she can go really high, that it's cheesy singing, and that her OWN singing is much better than yours, JUST because she doesn't do anything to *try* and make her voice sound better. She also might be jealous that you can do certain things with your voice, and because she can't do it, she automatically decides that it's bad. Or maybe her favorite female vocalists singing styles sound nothing like yours. Maybe you add a jazzy sound to your voice, and the girl your singing too hates black girls/rap/jazz. I'm just saying. They would definitely not like your singing then, whereas someone who appreciates that sound could think you had some amazing talent. Girls might have different ideas of what sounds good. Also, they might just think it's very strange that you're singing to them, and it might make them feel uncomfortable. Maybe you were singing in a public place, and didn't notice a lot of people starting to look at you two when you opened your mouth. This may have upset the girl. Maybe the people looking are mean, and they made negative faces, and she would have felt stupid if she said you were good with all those people glaring at you like you should stop. Either way, it MIGHT not even be because you're a bad singer at all. People are snot-nosed self-centered jerks. They could just be trying to hurt your ego, since you think your good enough to sing in front of other people. They don't think they're good enough to sing anywhere but the shower. That's their issue. If you want true opinions, find people who listen to voices, like music teachers and other singers. Let them hear a recording on headphones instead of bursting out in song in public. Or show them privately. Give them your best. And take criticism. Ask what to do differently. Practice your scales, and look for voice training advice on youtube. It's free and good advice a lot of times. Mimic different styles, and always be willing to work on your voice, because there are probably things you do poorly. you might not enunciate words enough. Don't worry about being bad at some things, though. Just practice them like no tomorrow. It's a skill to be learned. You probably already have a great voice, so learn to do amazing things with your gift through practice.
