There is enough information about David Cook's music now, that it should be on its own page. I am assuming you are talking about the section "Post-Idol Career"? That information doesn't belong on a discography page. Discography pages are for listing information about their albums, EPs, singles, charted songs, and other information relavent to their music albums etc. This doesn't includes Tours however. It is very unlikely that an artist will go on enough tours to merit their own Tourography page, so they are listed in chronologically in their own section on the artist's main page. Also, once David has done more stuff, the category will change from "Post-Idol" to "2008-____" or something similar to that. But tere is not enough info yet.
