Very inspiring naat "Duniya Ke Ae Musafi" by Junaid Jamshed. People say thinking about Death is a sign of depression. I'm a Muslim and in my case it's an Inspiration.

Rasul Allah (sal Allahu alaihi wa sallam) said: "Remember often the Ender of Pleasures." [Nasai]

Those who sleep on velvet, will surely, one day sleep in soil. Kings and paupers alike will have a bed in the earth. Traveler through life, your destination is the grave. What you are traversing is two days journey.To remember death is like for a student to remember that there will be an exam at the end of the year. The more conscious he is of it, the more he will consistently prepare for it, and the better he will do when the time comes. He who parties away, heedless of his studies, will not fare well, and at the end of the year the exam will bring an end to his pleasures. It is recommended for everyone to frequently remember death, and to prepare for it by obeying Allah (subhana wa ta'ala) and repenting of his/her sins. A saying in Persian goes, "If childhood is spent in play, old age in laziness, and youth in mischief, when will one worship Allah?"
