Actually, I know what you're talking about, as it happens often to me. Last spring I was in a 170 mile bike ride for two days and couldn't get a piece of music I had practiced the night before out of my head--I was sort of on cruise control and nothing much else goes through your head out there other than the scenery and the pain, so I couldn't shake the tune. Learned it pretty well by the end of the ride, but I have no idea how to get rid of the tune until I listen to some more music or I get involved in something that makes me concentrate my thinking.
Has anyone answered the real question?
First, I want to say that the white-outfitted guys are at my front door. Second, these people(Ori, or Oritek Audio, Alex, of APL Hi-Fi, and Nuforce-I also have to mention Signal Cable and Mapleshade.) have led me to this situation. Does anybody have a strategy against what plays through your head, when you are away from your system? Believe it or not, this is what has preoccupied me for awhile. Does anyone, anywhere relate to this? If so, can you give me some kind of strategy here?
