Saavn.com is a great place to listen music and offers much wider version of songs than others like Gaana, Hungama, etc. Audio Quality of its song is also awesome .
Saavn also offers their services on App too. There you will also get a free trial of 1 week after that you will have to buy their subscription which is 120 INR per month or you can continue using their services via internet( you will not be able to listen songs offline when your subscription ends). I am using Saavn app from past 6 months and so far I do not have any major complaints. However it would be perfect if they pay attention to their users needs. Their feedback system / customer care is not much good . They will reply you positively but I think they just ignores the suggestions and requests. I have requested several times to get new songs / content which is unavailable to get requested but even after several weeks I didn’t found them.
Overall it is a good website. Around 10 times better than Gaana.com
