Bard stats

[Coridan]

So what's really the best place to focus stats on a Bard? I pumped it mostly into charisma (and I think the leftover went to stamina) on my wood elf bard. I'm level 22 now and with items I have 146 Charisma, but I hear that mez, lull and eventually charm are the only things affected by it, which isn't really a lot of songs. Certainly not as important as Int/Wis for other casters.

So what stats should I focus on raising? I've pumped up my strength by about 10 points for damage and carrying capacity, my Agi is about 98 and my Dex is 103. I got a runed bone fork so my saves are pretty decent now; just don't know what I should be building really, I'm all over the map.
