Tbh last year they released 2 Korean albums and just the 1 English song, so I don't think they've changed all that much. Nor do I see the 1D comparison either lool tf
Unfortunately it just seems if they want any Western acclaim (i.e. the Grammy the members are aiming for), the catchy upbeat songs seem to capture a wider audience compared to the more personal and 'deeper' Korean songs that fans prefer. I'm sure they'll still release the music they're known for (and let's face it, prefer probably) further down the line this year.
In other words, they are selling the soul in their music for a trophy that means nowt.
