I say we should mourn the death of good singing. Good singing gasped its last ragged breath in the late 80s, if you ask me. At some point, bad singers convinced people that "singing bad is cool". Metalica, Nivana, Bruce Springstien, and ACDCs lead singer, whomever he is: they can't sing at all. The good singers (and pardon the spelling): Lou Rawls, Marvin Gaye, Lionel Richie, the Doobie Brothers, Stevie Wonder, and many many more; these folks had a quality product to sell.
Regarding Janice Joplin...ok, she sounded like she gargled with whiskey - but she did more in 3-4 minutes of vocalizing than Kurt could ever hope for.
ACDC, Bad singers: though good singing is dead, I still find myself liking much of it - Nirvana sucked, their clones, and new music in general (especially modern R&B) suck, though.

I used to be a huge Lou Reed fan, but the boy can't sing his way out of a paper bag.
