I also lost interest in Bruce after Born in the USA. I don't see anything "bad" about that.

Springsteen has continued his musical journey in one direction, I moved in a slightly different direction. Over time we've drifted apart. I can still respect his amazing talent without being able to personally connect with the music like I used to.

Sting, Robert Plant, even my beloved Rush (and many others). We all diverged at some point and to different degrees, yet I recognize they are all still incredible musicians.
