Assalamu alaikum my dear brother

First of all I am very happy to read your post and find your thoughts very outstanding and different from us because you told us that as a life is much busy and we have not enough time to do something for our leisure activity obviously it's very true life is very busy nowadays moreover as you told that music is haram in Islam and you prefer to read books over listening music.

Definitely reading books is a good habit it's also source of entertainment if we adopted as a hobby it can give us source of information knowledge and also mental peace as compared to music as a depends up on the priorities and the thinking too.

I appreciate your valuable thought in present era where's we couldn't consider these thought much important.

Good luck
