Not many people want to play bard because it can be really annoying, not because it doesn't have a new, original song.

Take Daurdabla owners for example. You go into morimar delve, sing your 3-4 songs then everyone goes off to fight. Someone pulls an eft, and the eft does dispelga TP move. All you see in the chat log is that everyone lost 1 song. Now you have to re-sing all your songs, and you have to sing them all with daurdabla again, so that the songs don't just over-write songs that didn't get dispelled.

Not to mention the 1 guy that always runs from you when you start singing.
