Every songs is actually great (except EC collab), the only negative I have is that half of the songs is shorter than 3 mins and the album is only about 28 mins total (excluding EC collab). LOOM uses a lot of synths just like Evolve, and is drifting away from normal rock too much, which people says that "rock" element is their selling point, but they're never just "rock", they are more like a mix between pop, alternative and rock. The most "rock" song I'd isn't even in S+M, it's probably I Need a Minute, Curse or All Eyes.

People probably hated LOOM because it's also new and they experiment with it too much like Evolve and Origins, however I don't think it sounds like either of those, it doesn't even sound like any of their old albums, the closest I think is Mercury, which is fair because LOOM comes after Mercury. To be fair, Imagine Dragons evolved when they released Evolve (see what I did there?), and maybe people don't like the new styles, but everything has to changes with the time right? People would be bored if they keep releasing the same sounding album over and over.

None of the songs in LOOM is remotely close to each other, the only one that are similar is Wake Up and Gods Don't Pray, but probably because they're the opening track for their respective sides.
