Lyric discussion by Dubious Merit 

"the singing of the stars" - the static you hear on the dial between radio stations is the leftover radiation from the Big Bang, but it's a parallel with the singing of (music) stars on the stations, who might be long gone but whose recorded songs create the impression that they're still alive and singing.

This ties in with the fourth verse, about the blood in one's ears sounding like applause (this can be an indication of high blood pressure); things sound better and more interesting than they currently are. I don't know how to tie in the first three verses, though.
