Ofcourse RR, you are more than welcome. If we are able to find the release dates & correct (my) errors in the list, we can bringout the milestone films. I am going to take time in a steady basis to evolve this list :

V1 - Film / year / release date
V2 - V1 + director / casts / Label / Banner
V3 - V2 + songs / singers for each film
V4 - V3 + Ragas

Just an humble request, if the file undergoes any modification, please rename it as 'V1.x' respectively, as we all can follow the current version.
