I think Karan johar is that director who simply work on his movies screenplay and bla bla but the things he is more perfectly choices songs for his because songs are one thing which gives a movie a highly and low level standard. Thats why karan johar’s every movie’s songs going blockbuster hits before releasing the movie . Every song of ae dil hai mushkil movie describe something in life. I can say that every song is my favourite song. especially Channa mereya and others are ae dil hai mushkil title song is awesome, bulleya song is also very good. alizeh song is much better. Most of the songs sung by arijit singh so this is obvious that songs going hits in playlist. Everyone loves the music of the songs.
