Have a music night. Select 5 different secular artists/groups. Place one artist/group per room. Give the youth autograph books. Tell them they need to get every artist/groups autograph. Get your Sr. High group involved, have them play the artists/groups (Spice Girls, Backstreet Boys, etc) The security guards take the autographs from the youth. In order to win they must have all the autographs, which will be impossible, because you will take one or more away from them as they run from room to room. Build your devotional around what is good music, and have them come up with the criteria, but you may have to guide them. Then play a song from each of the artists/groups you had present, and discuss if it fits the criteria you have listed. You can make this as big an event as you want, we used two youth group meetings for this topic. Get your actors to really play the roles of the artists well, etc. Expand and mold this to your group. Its a great way of discussing this all important area of the life of a youth.
