As far as music concerned, I think it is totally about personal choice some people like old songs of singers like Kishore Kumar, Mohmad rafi some prefer songs of singers like Arijit singh, Mika singh, ankit tiwari and many more in case of bollywood music.
Some people likes gazals while some prefer foreign music from bands like one direction and singers like Taylor Swift,Selena golmz,Justin bieber.
I think author should have mentioned what kind of music is preferred by him, without this information this question seems incomplete.
Other than songs music preferences can be based on musical instruments some people like guitars,flutes , haramoniyam, voilen and this list goes on increasing.

Even this challenging situation would ease
Some may like hindi music while some may like english songs while some may like regional music. Some prefer devotional songs while some prefer instrumental. Sometimes it also depends on our mood.
So it totally is a matter of choice.
But if you are asking about best music album as per the top charts declared as per rankings then that is a different thing.
Infact you tend to like different types of music, as per your moods too.
I am a die hard fan of Jagjit Singh
Miss him and his soothing voice.
