Disclaimer : I play a bard.
I will start by saying I think that bard song as it is is actually weaker than I think it should be, I know it sounds odd, but I'll explain.
Up until lvl 14 (14!!) the combat bonuses are +1 ab/ac/dmg/saves/skills. If to compare it to the other party buff class (warden), they will have by now +3 ac bonus that -stacks- with other sources (unlike a bard's deflection bonus), +2 on ab/dmg, and their capstone martial ability (overpower/shield wall).
There are exactly two things that scale significantly as the bard goes through these lvls, and that is the temporary hp and duration. The way this is most effectively utilized is by reactivating bardsong midfight to refresh the THP. Each such time costs a bard song use, spends a round and smacks 8 hp on your party. It's not gamebreaking, but it can help in tight situations.
Aside of two of the bardsong bonus feat song abilities who actually tweak the main bardsong, all bard song abilities will require bard song use seperately from the main song, which means the same pool is going to be used with no means of refreshing it. This is also true for curse song. This means that pumping up people with the other bard abilities (which last 1-1.5 min depends on lingering) will -quickly- drain your uses.
On the issue of curse song : in practice, I find curse song to be -far- weaker than the theoretical calculation might imply. If anyone thinks standing in the middle of an enemy crowd and spamming an average of 22.5/round at lvl 18(!) for 18 rounds while everyone's agro turns to you and they all gunk you while you can't do anything else is a good idea, be my guest. I dont think it's a good tactic at all, and Im understating. (And just to give an impression, on the current lvl cap it'l be 10 dmg on average per round, most times you're better just hitting with your weapon).
So, being able to use just spend one bardsong use for the regular song due to the long duration is a blessing and also a way to make sure the bard is able to give his main class contribution throughout the whole fight as imo it should be. I do agree it sometimes gets silly when a bard is buffing a party with a song and just sends them off so I agree it makes much more sense to limit the effects to the bard's proximity.
So in my opinion in short : Bardsong bonuses aren't that significant, Duration is fine as long as bard song uses cant be replenished, Curse song spam is an ineffective and suicidal tactic in most cases so not really a problem, song affecting only while the bard is around makes more sense.
