Safe? I think the concepts and trying for something different is the real challenge. I'd rather use an artist again and again if it creates what I'm looking for. Honestly, not having a concept is playing it safe. Not trying for something special is safe. The payoff is greater when a concept is accepted and enjoyed by others. How can you say some of us are playing it safe when you didn't even have a concept to your playlist? I'd like to think that even though I have used artists multiple times that one of those times made someone pursue an artist further. More importantly, I'd like to think that everyone of my playlists have been unique. To The Stars, A Fire Cried No Hiding Place isn't anything like The Black Forest and neither are like A Little Chopin/Nightflight. Those were risks in subject and in pushing what a playlist could do. The concepts and structure are where the risks are.
