Here is a constructive idea that would likely make most bards happier,
return these songs to a being a viable option, and maintain Enchanters
current position with respect to crowd control.

Make the songs in question require an instrument much the way that Sonorous
Clouding currently does. Make a string instrument mandatory for Lucid
Lullaby and a wind instrument mandatory for Pixie Strike. At the same time
remove the secondary resist that has rendered these spellsongs impotent.

I think this change is in line with the bardic theme, makes the songs a
viable option, and maintains the necessary amount of balance over these
songs.

Ideas?
