A writer for "Nitro" was skeptical of Paparizou's musical ability, writing in a piece titled "If the World Was Fair" that her image and the aid of backing vocalists should be recognized as playing a significant role for Paparizou. Pavlos Zervas of Music Corner wrote favourably of her voice; he said that on the "Euro Edition" EP, it was "adaptable" and "pliable" to the necessities of each of the songs, from the ballads to the uptempo ones. Critic Georgia Laimou of "Eleftheros Typos" disagreed with Zervas. Laimou found her deliveries monotonous and possessing no nuances between songs and styles. She also said that Paparizou's limited range meant she had to repeat a similar set of notes. Paparizou's tendency to strain her voice through oversingingspecifically shoutingwhich grew worse with age has been a common complaint. Laimou said that particularly after her Eurovision victory, Paparizou sang with a new-found confidence and force. Circa 2008, critics noticed an improvement in her voice and said that the album "Vrisko To Logo Na Zo" contained her best vocal performance.
