If you're a fan of Bollywood musicals, you know all about Asha Bhosle. She's not an actor -- she's a singer. She's known as THE voice of Bollywood. Asha Bohsle's been at it a long time. She began as a teenager. This year, she's celebrating her 75th birthday with a soon-to-be-released CD -- and a world tour. Asha Bhosle recently stopped by our studio to sing for us.

BHOSLE: (Sings) Tum Jo Mele - My heart says something. I can't explain you. You must understand my feelings.

MULLINS: And why did you want this as one of your bonus tracks on your upcoming CD?

BHOSLE: Because it's my birthday and I can do what I wish.

MULLINS: How many songs have you recorded?
BHOSLE: 13,000. This is a world record, I know that. I sing two, three songs a day. Sometimes five. I start my day at 10 o'clock or 9 until night 2 or 3 o'clock. I sleep four or five hours a night. I'm a workaholic.

MULLINS: There are many artists who will not sing anymore. In terms of the profession it's so much has changed. Bollywood must be nothing like it was when you started.

BHOSLE: Yes, there's a drastic change in Bollywood, everywhere. But, my voice is good because of my practise in Indian classical music. Every morning I do my practise. (sings scales). I do this every morning for an hour or two.

MULLINS: Did you make a conscience decision to sing with modern artists like Boy George?

BHOSLE: I like that. I like new singers, new language, and go in their boundary. I like that.

MULLLINS: What was the challenge in working with Boy George, the Kronos Quartet, or Michael Stipe?

BHOSLE: Everyday there is a challenge because the songs are in different styles, different scales. Sometimes you are singing sad songs, sometimes you have to sing fast songs.
