Singer Alisha Chinai, with chartbusters like "Kajra re" ("Bunty Aur Babli") and "Tera hone laga hoon" ("Ajab Prem Ki Ghazab Kahani") to her name, thinks playback singing is ridiculous and says she can't do it any more at any cost.

"Aishwarya and Katrina are beautiful women. But sorry, I didn't enjoy watching them pretending to sing my songs 'Kajra re' and 'Tera hone laga'. My God! It's so ridiculous! Would you ever see Julia Robert singing in Madonna's voice? Over here this practice of ghost voices just spooks me out, man. I can't do it, sorry," she said.
