Well I understand.. It's a personal choice. I chose Mizo language just because it's a little different than Hindi songs, and when I had one of my favorite Hindi songs last open it didn't do well so went with mizo which boasts of a 6th place finish at Open 20' .
Now that it didn't do well I might run out of options. Coz Annual 21' entry (English) was also pretty good and didn't get the points it deserved .
So next open have to think twice should I enter into contest in the first place (considering the best Indian songs especially Hindi don't really go well outside the Indian Diaspora) . Then if I do enter Hindi may not be a option. Maybe some very new language not used in TISC yet.
