Hi, I am Shadab Zafar, a CS undergrad from India.
I found out about MusicBrainz Picard in Nov 2013 while looking for a tool to tag my songs. A friend then told me that there was a GSoC project on the same tool, I applied for the project and got selected so during 2014's summer, I worked on creating the current Picard's site & API and adding Plugin Download features to Picard.
I have a lot of old untagged bollywood music, I've thought of adding it many times, but just couldn't get it done.
Some releases that I found on iTunes but are not in MB (last I checked) - Mickey Virus, Samrat Co., Toon To Thehre Pardesi, Total Siyapa, Main Tera Hero, Best of Me by Mohit Chauhan, Coke Studio (Coke studio has a lot of CD releases, almost all of which are missing)
