this is the description of the theme that you can use for Drug music :
Semi-open theme in which you are asked to send a song that you think would work best when drugged, or, to make it simpler if you have no idea how psychotropic drugs can work up on you (and don't do drugs, people, please - just use your imagination here), a song that you feel would sound even better under the influence because your mind is open to things your "normal" self won't allow you to enjoy. The songs can have in their titles or in the lyrics references to drugs but that is not mandatory at all.
The description of the theme is left purposedly vague because the goal is to see and hear each player's interpretation of "drug music." Ideally, you should privilege "psy" kind of songs, but if you really don't find anything of that sort, you can go with songs like Winehouse's "Rehab", for instance, which are literally about drugs and not very "psy," musically. However, you would be hard pressed to find a Céline Dion song that could fit such a description; in such a case, the manager will probably play his/her role and will refuse your entry. None of her songs are "psy inducing" or have anything to do with drugs, in any way, as far as it is known.
All in all, when picking your song, just imagine what "drug music" sounds like in our collective consciousness/culture.
And, please, write an explaination in your PM to the manager when you send your picked song as to why you think it fits the theme, it will help the manager and us too, listeners, to understand your choice.
Translation of all this: AP wants psy trance, not rock or rap songs talking about drugs.
