I agree, when I heard a harmonizer for the first time, I could not believe they would get so popular in POP music. Having the looks is as important if not more important to be a successful POP singer. Who needs a voice anymore? Push the IMAGE and let the Harmonizers and Lip Synch tapes cover the product.
I still have faith a real voice will rise to the surface every so often, but the Britney's, Ashley's and Milli Vanilli's are going to sale as long as the public doesn't care. Maybe the people will want the real thing if they knew better.
