no that couldn't be farther from the truth... everyone can't sound good, the auto tune plug-ins can help out a lot though. Listen to hillary duff... the girl cannot sing, even with all that auto tune her voice still sounds like crap, I know for a fact Kalomira has a lot more talent than hillary duff, britney spears and the rest of those teen pop singers. Sure, she's no mariah carey, whitney houston... or even christina aguilera... but to say she's horrible is just unfair.
All I can tell you about her is she's a great person, hard working and could brighten up a room instantly and if you met her, you would find it hard to say anything negative about her ever again.
