As i overhauled the Bardic Music ability i also had a look at the Bardic Music feats from Complete Adventure and Complete Scoundral, and found them unreasonably expensive in use or simply too weak to ever spend a feat on. Thus i redesigned ALL of them in a uniform manner consistent with the method of redesign i used for the standard Bardic Music abilities of the Bard.
In addition to the Bardic Music Feats, i also revisited the Lingering Song feat, which would have made no sense with the new Bardic Music style. The feat now provides the Lingering Effect of 5 rounds, where before there was non, but only to Bardic Songs that last indefinitely while maintaining them.
I also added another feat: Loud Musician. This feat (though technically not a Bardic Music feat) doubles the range of all Bardic Music abilities.
