My favourite Bollywood film music collections so far have been Indiavision (2005) and now Bollywood Funk (2000, on UK's Outcaste Records).
More groovy Hindi weirdness from the 60s, 70s and 80s; with blaxploitation film wah-wah guitars, analogue synths, big orchestral interludes, the sugar-sweet vocals from the playback singer legends like Asha Bhosle and Lata Mangeshkar, and some feral yells and insane laughter!
Film clips to some of these tracks found from YouTube:
'Dum Maro Dum'
- from Hare Krishna Hare Rama (1971), sung by Asha Bhosle
- from Yaadon Ki Baraat (1973), sung by Asha Bhosle and Kishore Kumar
'Chura Liya Hai'
- from Yaadon Ki Baarat (1973), sung by Asha Bhosle and Mohammed Rafi
'Pyar Zindagi Hai'
- from Muqaddar Ka Sikandar (1978), sung by Asha Bhosle, Lata Mangeshkar and Mahendra Kapoor
