Yes, skits can add something to a song or album. However this is when the skits actually, you know... have something to do with a song or the album. The "My World Intro" for instance was nice skit and is one of the few skits that I'll actually play. Even when a skit does "tell a story" or otherwise fits into the album... it'll still only be played by me once. I don't like skits. Can be interesting on a first listen through, then... just a waste or time and space.
However the issue here is... 6's and 7's was filled with bullshit skits. Hell, the Pledge... twice? Actually, I'm surprised he didn't put it on there 6 times, each once fitted to a different genre such as Rock or Country to fit the whole "my music is for everybody" dream he has. Why not get those country fans in on that cult-ish crap?
