For South Indian, I considered four languages – Tamil, Telugu, Kannada & Malayalam. All the songs mentioned below are from the movies released in one month – May 2011.
The selection is my own, and I tried my best to listen to most of the songs released in May 2011. But since I was not able to listen to certain songs online, I might not have included them.
Also understand that musical tastes differ from person to person. But since all the below songs have been selected after multiple levels of scrutiny, they must be good! Try listening to songs in languages you are not familiar.
The songs below have been linked to sources from where you can listen to them Online.
