Some music is particularly appealing, or even only appreciable, when listening to it in some sort of altered mental state. For the sake of discretion let us leave aside the how/why/legality of the way the altered state was derived. Some of my favorites: Air-Surfing On A Rocket It's an incredible, baroque space wonderland. The song actually induces something similar to the titular activity. TV on the Radio-Staring At The Sun The whole song has a certain sense of inescapability, or inevitability. The beat just rolls forward, unstoppable, and sucks you in in the process ATB-Don't Stop Makes your world into the most pleasant game of Mario Kart ever Those are all I can come up with off the top of my head. I'll look at my mp3 player and post some more later. Please share your favorites.
