music = songs?
There can be no music without a defined verse/chorus/verse/chorus/bridge/chorus arrangement?
I can get behind disliking the album. Really, it's bizarre, especially if you're used to hearing something entirely different from the band. But your definition of music is so absurdly narrow I've got to say something.
Comparing October to Passengers doesn't even work because their goals are v ery different. October, outside of October and Scarlet is a very traditional post-punk record that frankly isn't very well written. There are a fistful of really great songs, but for the most part they didn't write very memorable material. Passengers can't be rated the same way because, yeah, it doesn't follow the same formula. And yet, it's a far more memorable, coherent, unique creation. Just because one album has songs and the other doesn't, that doesn't make the songs any good, nor does it make the experiments inherently awful. Take the albums as they are without forcing the same expectations on both of them.
Or don't, and miss out on a lot of great music. Passengers is probably the 800th strangest album I've ever heard, so it's really only uphill from there when it comes to electronic/ambient releases.
