Becky Krill teams with Bjorn Majestik and Homeboy Sandman for “Smile,” a collaboration that shines from the very first seconds. It’s a good way to finish off summer, and the song has a relaxed feel with a soft romantic glow that doesn’t seem too overdone. “Smile” is a reminder that small gestures have lasting power, and it’s more than a seasonal anthem. Its positivity is refreshing, and it’s a track that leaves listeners lighter than it found them.
