I ran across this last night and I thought it would be interesting to post here.

In January 2010, NPR will launch a year-long exploration of 50 great voices in recorded history. The series isn’t an attempt to catalog the so-called “greatest” singers. Instead, we hope to discover and re-discover awe-inspiring vocalists from around the world and across time. We asked you to nominate artists for the series and we received thousands of options. NPR and a panel of experts are in the process of whittling them down to about 100 singers — a mix of familiar names and surprising discoveries. Explore some of the nominated voices below, choose five favorites you think should be included in the final 50 and tell us why.

Take the time to listen to some iconic voices from the past century… I might even tell you my top five if you comment about yours.  If the flash application doesn’t work for some reason just check out the original site.
