Diana Ross was on Oprah today and it was mentioned that while she has been nominated for Grammys before...she has never won.
So I did a little research and decided to create a poll as to whose music you think has most deserved to have won a Grammy at some point.
Others who did not win a Grammy for any specific recording or album:
Dusty Springfield (2001 Grammy Hall of Fame award)
Grateful Dead (2007 Lifetime Acheivement)
Janis Joplin (2005 Lifetime Acheivement)
Jimi Hendrix (1992 Lifetime Acheivement)
Sly and the Family Stone (a song from a tribute album to them won a Grammy)
Neil Young won his first Grammy this year.
David Bowie has won two Grammys, one for a 1985 video and in 2006 a Lifetime Acheivement Award (but none for any specific musical recording).
