As an album, 'Katamarayudu' is a balanced one. So far, one hero-centric song, two duets (including 'Emo Emo') and a party-type song has been released.

Anup Rubens' duets have certain characteristics. They are breezy, they are not ambitious, they don't necessarily have a specific, clear-cut ring about them. 'Emo Emo', with all these qualities intact, is enjoyable.

Shreya Goshal is the behind-the-screen princess of the number. May her mellifluous voice prove lucky. Arman Malik does a fine job of sounding both youngish and apt for Pawan Kalyan.

Anantha Sriram gets to pen a song in the 'Nee Chepakallu' mold. While the love-struck boy accuses the lady of one or more sins, she herself is clueless about the romantic assault she has delivered.

All in all, a duet that might just sound better when watched on the big screen, courtesy the Shruti-Pawan pair.
