Bard songs on Live?

[AndMetal]

I've been digging into the spells_us.txt a little more trying to figure out some more unknowns. While looking at field 142, which is the same as Unknown 130 on Lucy, I noticed that a lot of bard buff songs, in addition to a lot of teleport spells, have a value of 0.

Anyways, my question is this: does anyone know, for sure, if beneficial bard spells on Live generate aggro? For some reason I though they used to, then was changed, but I couldn't find reference to it in the patch logs.

If so, I think this might be a hate modifier (hate *= field142).
