I have read almost all quick transmigration novels and system world hopping type of novels, so much that have started to forget some characteristics of each. I was watching some music talent show videos and I remembered that I have read a world transmigration novel where the female lead transmigrates into the body of a girl who is undertaking a singing competition. I think that in the audition she started with a cover song and was directly transfered to the finals where she was against a girl who could write originals and this everyone thought she was gonna win, but at the end the MC also sings an original and wins the show. I think she also had a friend who helped her with the costumes and stuff. Does it ring a bell? I am really struggling to remember where I have read it.
