| All-Reviews.com (PlayStation) | Tom Allen | "Die-hard music fans may like it, especially for the two-player co-op and two-player competitive modes, but I'm going to pass." | 2.0 out of 4 |
| Absolute-PlayStation.com (PlayStation) | Tom | "Parappa rapped, but Lammy jams! Check out yet another very cool musical action game that will have your feet tapping and your fingers working overtime to keep the beat!" | 85 out of 100 |
