Don't do this^. Put all into dexterity. Songs are situational at best. The Battle Voice duration should be enough to to take care of what the party needs. After BV is over drop the song. Foe's Requiem is only really helpful for BLMs and it does squat for Wind Bite and Flaming Arrow.
BRD is only a support class when the party needs it (which is not much, mostly towards the end of fights) any other time (aka most of the time) you are just a DD so spec for that.
