I suppose the situation is different if the album is a "concept album" so to speak but, you know, that would be a whole different kind of project than what I would do, personally.
what i feel is, if you're gonna have 'concept' on an 'album', at least crank up the 'concept' until it's not an album anymore. if it's still an 'album' then i feel the concept wasn't strong enough. kind of like jet fuel melting steel beams. if the beams didn't melt, the jet fuel wasn't strong enough. etc.
