I think the bottom line is this: 1D will never gain a larger appeal if they stick with the songs like Kiss You and Best Song Ever which are catchy, but very juvenile and immature. And it looks like they are not changing the formula anytime soon as I saw a headline today with one of them saying their new single will be similar to Best Song Ever. I would have suspected at least tiny growth by 3rd album, but I guess Simon is sticking to that saying "if it ain't broken, don't fix it".

About their writing... When you have 5-6 songwriters credited before your name, this shows they had a small input in those songs. Westlife didn't write a lot, maybe 20 songs in their entire career, but at least you can say they wrote the songs because they were credited first, while they wrote a few songs on their own.

But you are right, 1D are singers and they don't have to write - I just find it funny when some 1D or The Wanted fans keep saying they are also songwriters when it is pretty clear their input is small.

Why the hell would you change a winning forumla when it is making them millions? They're not some amazing band that write all their own records, and I don't think they've ever claimed to do that. Can you imagine if they decided to do incorporate some trap/dubstep, or have a featured artist. It's immature bubblegum pop about being young. I don't think they care about larger appeal when everyone talks about them and they still make millions of pounds/dollars.

I'm not saying they should completely change, but it wouldn't harm them if they do have 2-3 more mature songs on the way - their fans will grow with them, so slight change should happen at one point. Plus, every acts tries to bring something new with each album, so it would be good for them to do that and not record the same old thing.
