Early levels the basic 'Inspire Courage' song is all you really have to use, regardless of campaign the rest are pretty situational regardless of familiarity with the game.

That's actually the main benefit, because if you are lost and not sure what to do you always have that fall back.

And when not singing, at least at early levels, you can still jump in and help with basic combat and not drag everyone down.

Also, that or the alchemist are your best bets at learning how to be a caster without playing a full caster as a newcomer. I stand by my pick of Bard being a good beginnner class. :p
