I don't think they plan things well in advance. Back in 1989, when they began work on No Prayer, Harry decided that it should be a more direct album just because he didn't want to spend too much time in the studio and that he felt the urge to deliver new music. This was just the feel of the moment that dictated the album orientation. Smith and Murray made it clear in recent interviews that they don't know in advance what an album would sound like, Murray even adding that, MAYBE, Harry has something in mind, but only him. As for the next album, I'd like it to be a well polished record, something they are fully and truly satisfied of. It maybe that last one ever, after all, so it MUST be something memorable.
