@Alex Newman I see. Yeah, I was slightly confused by your premise. Sorry If I answered outside of your intended query. To course correct here Ill say the following: naturally what I listen to will be genre specific so the list is endless but two things that I do that might be unique are 1) using lots of the diegetic music (folk songs, choral works, solo period instruments etc) which adds a nice meta-layer to the RP. This is particularly easy if the setting is modern (60s, Vietnam era particularly good). 2) I will use music to begin/end scenes and sessions ala a TV show. So having a 'main theme' to start of the session and get people 'in the mood'. Or to play the CSI: sting or some audio clue to nudge the players in such a way as to say "you have found all the important clues here". Hope this better answers your question. Best, Jay
