Gerua (which I've had for a while), Janam Janam and Daayre all get 4.5/5 from me. These songs are just soul-pleasing and wonderful! Arijit Singh has delivered yet again!
All of the other songs get 2/5 though. They don't really appeal to me at all.
Overall I'd give the album 3.75/5. It contains 3 gems as well as 3 not-so-good songs.
