The music creation feature of the game, while seen as a useful addition to the game, was found to be difficult to use, suffered from on-screen lag that could interfere with song creation, and the quality of the resulting songs were compared to ring tones for cell phones. The character customization in "World Tour" was generally seen as an improvement over the limitations of "Rock Band". However, reviewers noted that the use of the real-life celebrities against the cartoon-like visuals, along with the emphasis on the band and not individual players, made their presence "anachronistic".
