I usually start from movie soundtracks and work outward. Bend It Like Beckham, The Guru, and Monsoon Wedding are good ones to start out with. I've got a lot of Darshan, Panjabi MC, and Jasbir Jassi on my iPod right now.

Hee. All this talk of Indian dance music makes me want to pick up another CD from Borders before I go home today. :)
