Dil Se is an Indian film directed by Mani Ratnam, one entry in his loose trilogy of contemporary terrorism, mixed of course with the melodramatic roller coaster ride we've come to expect with Bollywood. It was, and still remains, an experimental film in Indian cinema. You can watch the whole film on Youtube here.
Notably, the film is accentuated by arrangements by the inimitable AR Rahman, resulting in what I believe is one of the best music albums he has ever made. (Even the background soundtrack in this movie was amazing... if only I could find them in streaming format.)
Here's a small playlist with the songs from this film.
