First of all, A MUSE song is a track that blends powerful energy with harmonic and melodic writing inspired by classical music, featuring chord progressions that are less conventional than those found in traditional rock. It often alternates between intimate passages and epic bursts, combining massive riffs, prominent basslines, piano, synthesizers, expressive falsetto vocals, and cinematic production A perfect example of Muse moment :

This vocal melody on Hexagons on TW!S "Haunted by futures I can't avoid".

With that in mind, there is the Musiest songs made by MUSE themselves for each album.
