MuseCritic

MuseCritic is introduced in MuseCritic: Learning Multi-Aspect Song Rewards through Natural-Language Aesthetic Critiques.

MuseCritic is a semi-scalar reward model for long-form song evaluation. Given a song and an aesthetic evaluation rubric, the model first generates a natural-language critique covering five dimensions and then predicts five continuous scores in the interval (1, 5):

• Overall coherence
• Musicality
• Memorability
• Structural clarity
• Vocal naturalness
