NPR is doing 50 great voices theme and featured Asha Bhosle yesterday. They had featured Nusrat Fateh Ali Khan last month as well. Be sure to check out the full stories. Here is a blurb from Asha's. 

"The next singer in our 50 Great Voices series may well be the most recorded artist of all time — unless you count her sister. Bollywood singer Asha Bhosle has recorded 12,000 songs and is featured on the soundtracks of more than 800 films. Her sister, Lata Mangeshkar, may have recorded even more. Their voices are easily recognized by a billion people in South Asia and around the world."
