Depends on the station. I've heard a bunch of different stuff, but Hindi, Urdu, Punjabi, Bengali and Gujarati stuff all crops up at least as far as I can tell.

Depends on the station. I've heard a bunch of different stuff, but Hindi, Urdu, Punjabi, Bengali and Gujarati stuff all crops up at least as far as I can tell. I'm also not terribly good at distinguishing them but can tell when I'm hearing Hindi or Urdu. Interesting that you mention the spectrum of Punjabi - I think I must have been taught some Punjabi-inflected Hindi which was very much like Hindi, and then had other people tell me they're completely different. Makes more sense now.
