I definitely agree that seriya thavaraa is just one of the worst pronounciations, but after knowing that Sandai kozhi (A. Ezhuthu) her diction is not ok.. Sadhana voice is mesmerising but some words make u think ayyo why she sang..I studied in Mumbai, have a track of all hindi songs including ARRs .. but comparing to mayilirage and suttum.. the ragam in suttum and the melody makes me vote for that...
