I've heard a lot about groups whose music you think have gotten worse as they release more things, but I'd like to hear groups that you would say have only gotten better!
Personally I'd say BTOB and MCND. BTOB fully leaned into the softer side and are known for their ballad type songs, but that wasn't always the case! For MCND I just think their sound has gotten a lot cleaner, and that was my main complaint with their first 3 albums.
