I can imagine in some years, you could see Freddy Mercury singing (and dancing) like Michael Jackson, for example "Bad" but with Freddy's voice... or things like that... At some point, if the artist are not well known, you will not be able to differentiate what is "real" and what not...
imo this kind of tech is useful to supplement the artist, not replace them. You listen to a singer because you know their voice more than anything. Bob Dylan was a pretty bad singer, but I listen to him because of some emotional connection.

After writing I think... does it matter?
