Since we are throwing the topic around, how about the following idea for a
new song:

Kelin's Notes of Indifference
Level: One of our missing songs
Instrument: Wind
Target: AE
Effect: When sung, makes all mobs in the zone indifferent to you. Mobs that
you are normally KOS to ignore you instead. Effect goes away if you attack
the mob. Undead are not affected by the song. When played with an
instrument, makes the effect party wide. Mobs get a resist check every
pulse while you are within their sight/aggro radius.
Analysis: Primary benefit is that it allows the bard to get bound in evil
cities without fear of getting attacked. Also allows the bard/group to
travel deep into dungeons bypassing mobs along the way.

Making it a party effect is probably asking for too much. A legitimate
possibility though if it affects the bard only.
