How many musicians actually listen to their own music on a regular basis?

I myself am a musician, and I’ve found that I listen to my own music quite frequently, sometimes with the intent of improving upon it, but sometimes because I really enjoy listening to the thoughts and ideas that I had running through my head at the time I was creating the song. I’ve always used my own songs somewhat like time-stamps, a perpetual journal of sorts, and whenever I have a sense of nostalgia (or when I need some good ‘ole advice from the “self of times past”) I listen to a song that I’ve written years ago.

I’m curious whether 1) you think that professional musicians, who pump out songs like they’re going out of style, listen to their own songs on a regular basis; and 2) whether any musicians out there personally listen to their own songs frequently?
