Feel it could be ideal if they it, so they still did the style they're known for and got popular with but also mixed in a few different new styles. I suppose it's pretty tough because people tend to get tired of the same stuff, but some people want the same stuff as that's their favourite, but also it's good to try new styles as a something possibly better could come from this. The only example i can currently think of though is The Killers, they tried something different with their Sawdust album and for me personally i try to pretend it doesn't exist :D (apart from the last track on it).
