IP ka ye concept koi samajh nahi aayega.

Maine socha tha ki "public domain" ka matlab toh hai ki koi bhi vahan ya medium ka khud ka Intellectual Property hai, jahan par dusre ka IP kaunse hai? Lekin agar ek composer ne ek gaana likha hai aur phir woh gaana public domain me aa gaya, toh yeh kaunse hai? Isme composer ka koi rights nahi rehta? Lekin agar us composer ne us gaane ke lyrics ne koi bhi modification ki hai, toh uske pas rights to hain, lekin kya vo yeh kahega ki vah gaana public domain se nahi likha? Aur agar composer ka koi bhi shaukeen nahi hai, toh isme rights kiske pas hain?
