Sleep the Black Spell uses a purple "smoke clouds" animation.
Sleep the Song uses an orange and purple "boiling orbs" animation and a wierd low-to-high pitched warbled sound effect. I believe it's the same as Balnaba's "Sleep Gas" sound effect and animation. The "boiling orbs" graphics effect is typified by the "Pollen" enemy attack
There is no straight up "Blind" spell. I know there is an enemy attack that sets blind status to the target...I can't remember but I think it's "Glare" or "Gaze" and is used by the big floating eye type monsters. In that case it's just a background flash visual effect and a pinging sound effect. That's what you'd probably have to use as his song. Blind is also set in the multiple status Marlboro bad breath attack. I think that monster must have been created and named by someone that didn't like American Marlboro cigarettes

However that might be what you're thinking as it's the "smoke clouds" animation but it's either yellow or green (IIRC Yellow).
Mute the Spell uses a the "smoke clouds" animation but it ends with some animated dialog balloons with ellipses in them to signify unable to speak...I guess. It's also got a unique sound effect.
Curse the Enemy Attack Spell uses a red and purple "boiling orbs" animation and a chugging sound effect. It sounds the same and looks the same as the "Pollen" attack but with a different palette. I just now made that Edward's "fourth" song using Phoenix's offsets and that's what I got after testing it, but I had also played with it before as I have made the Ancient Sword able to cast that particular "Curse" spell.
Which BTW, they work like a champ Phoenix. In my current hack Eddie now sings four songs, including curse (I'm just going to leave that), and never misses since he has four normal songs. Thanks for decrypting this stuff!
