Saavn is the best music streaming service available in india.Gaana is also there but I would prefer Saavn over Gaana.The User interface of Saavn is very simple and good.
There are huge collection of new and old songs of many different languages in saavn.
The audio quality of songs in saavn is very good.You can even download songs in you mobile for offline use.The drawback of saavn is user cannot rate the songs.
I would recommend Saavn over other music streaming services.Daily I will listen songs on saavn only because I like its interface and sound quality.
