Bard mana songs

[Veleria]

As a 53 bard what mana songs will give the best regen to my group I have a Lute of the howler and can generally run 3 songs without issues. Does the 55 mana song change what I use, I'm having trouble understanding the differences because I can't see them affect myself and the info is a bit confusing on the wiki. What 3 songs would you run in an xp group assuming healer 2 casters and 2 melees as a base?

Thanks for your help.
