For a weaker Bard buff, and soloing... sure.
Party support of the Bard is more useful than this though, having more buff provided to the users.
Support bard is dead with this patch.
Anyone can cast overture whenever they need it and keep it up, barely spending 2 secs between every few spawns. In a whole party full of dmg dealers taking turn casting overture in an unobtrusive and efficient manner, there is no room for a specialized support bard.
Besides, the only music skill anyone ever wants to be played is overture... and whenever someone dares override it with another music skill, someone will do the right thing and cast overture again.
Edit: And before anyone says "but what about mages/alch, vivace is better!" NOPE. Overture now affects the added dmg from the new formulas, making it the more useful skill for them too.
