Screw those videos, I found this one about your lich in dota.. http://www.youtube.com/watch?v=4GuqB1BQVr4
Her non-altered man voice is teh sexy. Kesha without autotune. Sounds much better I don't even understand how people enjoy songs that are "enhanced" with shitty production gimmicks like autotune or any sort of modification. Kesha could sing some serious vocal trance or trip-hop with that amazing voice but it's wasted on making corporate pop music where they ruin it.
Not bad. Katy perry reminds me of Cher a bit when you don't hear the auto tune. really like that kesha song you posted , she really does sound better without the autotune. Then again that whole song sounds better than the official track.
