I'm the simple forgetful type, so my songs are descriptive, at least to me.
I also include my name as part of it, well.. just because!
A few of my renditions:
Nycah's Slow Song - slow mob, haste melee and casters, mana regen
Nycah's Invis Song - runspeed and invis
Nycah's Drowning Song - runspeed and water breathing
Nycah's Travel Song - runspeed, lev, invis.. named in honor of the EQ1 bardsong of the same name
Those are some. I just love the fact that almost every bard's songs are unique. Composing gives us so much freedom. I love it.
