Google now offering 4 month free trial for Google Play Music/YouTube Red | 9to5Google

Hat tip to the Verge for linking to this. 

If you already have Spotify, Apple Music, or what have you, YouTube Red is the real appeal. YouTube Red is YouTube without all the ads, plus some premium content that isn't available on YouTube Regular. 

With YouTube Red + Netflix, my daughter will have basically no frame of reference for commercials.
