We were in the car last month and a song came on and Soren said, "don't change it! I love this song!" and I thought that was so cute and he sounded so much older than 7 at that moment! He's never expressed any interest in music before then.
But this song lyrics say "Spiderman" and "Batman" so maybe that captured his attention?
Its "Something Just Like This" by the Chainsmokers. I have to admit it IS a pretty great song.
