no you think wrong, bard is pure class "material" and has much more love in DnD than in NWN where he is greatly pruned back basically into single ability.

It is true that bard was pruned back. But you are citing a 3.5 SRD which came after NWN pruned the bard class. The 3.0 SRD has most, but not all, of these song variations present in the 3.5 SRD. Those added in 3.5 were Song of Freedom, Inspire Heroics, and Mass Suggestion.
