Saajan is an amazing soundtrack, and Mujhe Neend Na Aaye is one of my all time favs (though it is not an original song =[ ). I am byfar the biggest fan in existence of Anu Malik, Jatin Lalit and Nadeem Shravan, their songs are completely ignored in today's world despite giving such amazing songs (though some songs are copied and inspired, but most bollywood music directors all have been at some point). I have an entire play list currently dedicated to most the amazing songs composed by Anu Malik (and will be making ones of J-L and N-S in the upcoming weeks)
I'd like to post the song behind my user name hehe

Refugee is byfar the most amazing soundtrack, and is #1 imo, it has the most soothing love songs I have heard and includes what I think is the most progressive uplifting sufi song Jise Tu Na Mila.
