ACL Line Up

I really like the ACL line up this year, and I think I will probably go for my first time this year. I really want to see Eminem and Outkast, I really like alot of their music, but if I could only see one, I would go to Eminem because I've heard more of his music and I think he is amazing. Some other bands I'm interested in seeing are Beck, Pearl Jam, Foster the People and maybe Childish. I'm sure there are other bands I would enjoy that are going to be there that I haven't listened to.
