Honestly, yes. The only three problems are getting the ridiculous PERFORM (ORATORY) bonuses (or having your DM nerf the DCs), the fact that you don't matter much after about level 12 until level 20, and of course the silly scaling of the PERFORM (ORATORY) DCs.
Quickening a BARDIC MUSIC ABILITY for free every round is way more powerful than people admit, and since there's no saving throw for many of the BARDIC MUSIC ABILITIES and they don't offer spell resistance, boss fights become pretty easy when the boss can't move and is constantly slowed.
Of course I guess a fourth problem would be how useless BARDIC MUSIC ABILITIES become when you can't see your target.
