Iron Maiden leader Bruce Dickinson is concerned that the band might be over-catering to their fans instead of pushing themselves creatively

Iron Maiden fans are on another level. And it’s a whole life term. I don’t support a football team but I look with astonishment at how supporters react. And I don’t think there’s a word for the level of commitment and devotion people have to a football club. And people have that same level of devotion to Iron Maiden. Part of me says - wow, that’s amazing. The artistic half of me - worries that maybe we don’t challenge ourselves artistically because we have this devoted following and they’re happy with the way we are. One reason for doing solo records is to push the envelope of what you can do emotionally and get out of the tram line. The tram lines are great. They’re quite broad, but they do exist.''
So Bruce do writes differently on purpose for his solo albums. I don't think Maiden have to change something in the songwriting, you know, the approach or to write something that different like Rain or Sonata. They could challenge themselves with songs like WOTW, Senjutsu or with sounds, but as Bruce said, they have to keep/respect the true Maiden style, which they will always do even in the ''different'' songs.
