What do Bollywood have to say about life? Here is a quick list of songs which define 'zindagi' as opposed to describing it. If I add the ones on what zindagi will be without you (Aandhi) and whether one should embrace zindagi or not (Sadma), then we are looking at 1733 songs here!
* Zindagi pyaar ka geet hain / Isse har dil ko gaana padega / Zindagi ghum ka sagar bhi hai / Hanske us paar jaana padega - Souten
* Zindagi ek safar hain suhana / Yahan kal kya ho kisne jaana - Andaz
* Zindagi ka safar, hain yeh kaisa safar / Koi samjha nahin, koi jaana nahin / Hain yeh kaisi dagar, chalte hain sab magar / Koi samjha nahin, koi jaana nahin - Safar
* Zindagi ek khel, koi pass koi fail / Khiladi hain koi, anadi hain koi - Seeta Aur Geeta
* Zindagi kaisi hain paheli haai / Kabhi to hansaye, kabhi yeh rulaye - Anand
* Zindagi hain ek juaa / Kabhi haar hi, kabhi jeet bhi / Yahan dushmanon ke bhid mein / Kabhi mil jayenge yaar bhi - Zindagi Ek Jua
Rajesh Khanna seems to be ruling the roost here with a 2/3rd majority. So, which one is your favourite zindagi song?
