One of the most prominent reasons for the long-term replayability of rhythm games is the opportunity for players to see their own progress after each challenge. At first you have difficulty keeping up with sequences of notes, but with practice your reflexes and sense of rhythm will develop greatly. Players learn to read movement patterns, manage their hand speed, and maintain accuracy over longer periods of time. Getting high scores, executing flawless combinations or hitting new milestones is a great feeling of success. Picking up a new skill everytime feels amazing. It makes you want to try to play on harder difficulties, and harder songs with tougher rhythms.
