Forget Lingering Song
I would not choose lingering song for any bard ever, period.
First of all, how many battles last longer (particularly at low levels) than 5 rounds?
(5 rounds is the default length of time a bard song lasts after you STOP singing).
Now, if you are an archer type bard, you can sing and shoot arrows all day. Sing for 20 rounds if you like. Don't need lingering song for that. In fact, you can swing a sword and sing at the same time as well. As long as you don't cast a spell, there is no reason to ever stop singing.
Or sing for 2 rounds, cast a spell, and start singing again. This uses up a bard song use per day, but you get one/level, and after level 2 you won't ever run out of them.
I mean seriously -- if you are a Bard5, how likely is it you will need more than 5 bardic song uses a day? Never, in my experience.
try this: level1: Point blank shot, precise shot
Level 3: rapid shot.
With (at later levels) greater magic weapon, haste, mirror image, cat's grace, etc. you will make an excellent archer. Plus you bard song applies to your own arrows (you are your own ally for the bard song bonus).
Have fun!
