User blog comment:Noctu2n/Why Song of Celerity Should not Considered to be Auto-Targeted/@comment-5266525-20151124011952

I'm (probably?) the one who designated it as auto-targeted to begin with as I believe my reasoning at the time was that Song of Celerity only has champions as valid targets, and not allied minions or pets. Other abilities that are auto-targeted under this definition are Morgana's Soul Shackles and Locket of the Iron Solari.

I acknowledge that I was wrong here though, as the bonuses are only a property of E's aura, which is point-blank AoE (aka. self-targeted).
