Khan Market Ka Karobar: Kaun Sa Artist Laga Bhagta Hai?

Okay guys, let's say, let's assume, koi bada music festival hota hai Khan Market mein (suno, ye possible hai nahi), aur koi local artist usmein stage par chadhta hai, lekin uske baad uske manager ne music album ka koi aisa change kar diya jaata hai jo original ko bahut badal deta hai. Ab is artist ko copyright aur trademark ka kya hoga? Main khud se pata nahi, lekin main soch raha hoon ke kya uske manager ko koi jama ho sakta hai? Aur agar artist ne manager se kuch puchha toh uska kya hoga?
