Vishal said it right Toshi ruined the pleasent atmosphere his song was supposed to create by all the negativity in his avi.
Toshi kept justifying the negativity in his avi by saying Dil Pe Mat Le Yaar. In the end Toshi ne khud Dil Pe Leya Li. He got in the Tashan aggressive mood before trying to sing a soft romantic number and totally messed it up.
The competitive attitude worked in Debo's favor because the mood of his song was the same and the judges also spoke of him positivelyšš¼ because of how Toshi had spoken about him.
Some people put Debo at fault but let's face the truth...Toshi increased his own chance of elimination by allowing his negativity to ruin his performance, his repo. with the judges and possibly his birthday.
