Retrofit is one big secret this week. Of course there's only one way to keep a secret between three people, but in music everybody knows what is up.  

Coverups, mysteries, silent crushes -- secrets come in all sizes starting with the dirty little ones. Want to know a secret?

Retrofit: Secrets airs Saturday at 5 p.m. 

Shhhh ... here's a companion playlist.
