Yuvan shankar raja is one of my favourite composer who has composed music for movies in Tamil, Telugu and Hindi.

Here is a list of some of his under-rated albums that he has composed.

Idam Porul Yaeval

This is an unreleased movie. This is the first movie were the director Seenu Ramasamy and action Vijay sethupathi collaborated with yuvan shankar raja.

Song Pick: Eerakkaathae, Kurunthogai

Nenjam Marapathillai

After long time director Selvaraghavan and Yuvan shankar raja collaborated for this movie. Each song in this album is quirky and it compliments the horror mood of the movie.

Song Pick: Maalai Varum Vennila, En Pondati Oorukku Poita
