Reflect and IRyS songs are technically challenging, Mori's filter you with the rap sections leaving no breathing space, Kiara's are just long blocks of speedy japanese aside from SPARKS
council songs don't really work without their voices (Daydream, Let Me Stay Here, A New Start), Play Dice is plain difficult and Astrogirl just makes people sad
