The music of a movie apart from Songs can make a big difference in the success of a movie. A song by Sid Sriram has made all the difference to Geeta Govindam.
In the same fashion, the music by Thaman has elevated the movie called Akhanda of Balakrishna. Anirudh is the in thing these days and Thaman from Devi Sri has become very routine for the movies.
There is talk that Thaman is copying and repeating his own tunes. Mani Sharma the veteran music director says that the directors must be rotated so that we get different kinds of tunes and that makes all the difference.
Some new directors are also giving good tunes and one of the examples is the Kushi movie by Vijay Devarakonda. The good songs in fact can give a massive opening to the movies.
There are times when the audience just went for the songs. So music is important and there is no second thought about it. At the same time, the background music will create the mood for the movie.
Now the song directors are different and the background score is done by a different director. Some movies have different directors for the songs also.
Right now Anirudh is the man in the limelight and he is doing the music for Devara of NTR. Thaman has become a regular in the movies of Trivikram Srinivas.
