Introduction to the list is here.
Two songs stand shoulder to shoulder at no. 24. er.. two-ish I should say. since one of them is a combination of tracks.
First is Aaj Din Chadhheya from Love Aaj Kal. I didn't like it all that much when I heard the album for the first time which came as a surprise to me because I have liked probably all Rahat Fateh Ali Khan songs that I have heard. But the song grew on me after I saw it in the movie.
The other tracks on no. 24 are the Dev-Chanda themes from Dev.D . I have always found it difficult to separate them, perhaps because I always tend to hear them consecutively. So, I am treating them as just one track here. I could only find theme 1 on youtube.
Update: Part 2 is here
