Question about bard songs.

[Nerdgasm]

So, we on DiabloQuest have an idea of making a said 'Aura' as a bard song, since in Diablo 2 you can only use one spell as your right click ability (granted, left click you can put another, but... meh).

Now, some bard songs are done by Singing, others are done by instruments... If I set an aura to lets say singing, and made everyone have singing, would it actually work? I don't see why not, but I've asked a few people and they don't understand Bard songs any better then I do... -.-'
