For the musical score of Machakaaran, director Thamizhvaanan teamed up with composer Yuvan Shankar Raja again, after the duo gave chart-topping songs in the director's previous venture Kalvanin Kadhali (2005).
She later worked several times with him to create popular songs like "Thee Pidikka" (Arinthum Ariyamalum), "Kudakooli" (Kalvanin Kadhali), "Money Money" (Thimiru) and "Oh..Oh..Ennanamo" (Chennai 600028).
