David Bowie is a very unusual person. When asked about the meaning of the song, he always gives a different answer, which to me says the song has no specific meaning. At a performance at Giants Stadium, Bowie stopped after singing the line, "Ain't there one damn song that can make me...", and dropped to the stage, where he stayed for 10 minutes. The crowd went nuts, but got concerned after a while. Bowie did it to see what kind of reaction he would get. Like I said earlier, David Bowie is a very unusual person.
