Your most played music/song

Is there a music or song (or more than one) that you play more often than all the others? Doesn't mean it's your favourite one, but it just keeps coming day after day, year after year as an addiction or a good old friend that shows up to test your system. 
For me, "Sultans of Swing" and "Telegraph Road", both from the live album "Alchemy" from Dire Straits, are making me company for almost 20 years on a weekly basis. 
Funny you would ask. I just finished commenting on an old thread about Mark Knopfler's "All the Road Running." I was surprised to read that some didn't like it. It has become one of my go-to CDs, out of a large collection. I think Emmylou Harris' contribution is just what the album needed.
According to my iTune play count the most played track is "Burn-In Tones" from the Sheffield/XLO Test disc.  The test disc has 3 of the top 10 most played tracks.  The most listened to music is David Baerwald's "Wondering".  Other artist in the top 10 played tracks are Dixie Chicks, Amy Winehouse, Seal and Lucinda Williams.  Statistics can be a little misleading since my go to track is Bryan Ferry's "The Right Stuff".
Roon reports the top 4 of my 25 Most Played (Since Jan 1, 2015)

1- Night Ride Home, Joni Michell

2- Bright Size Life, Pat Metheny

3- Ciaccona in G minor, for Violin and Piano, Jessica Lee

4- Homecoming, Ray LaMontagne

I wouldn't have guessed any of those. Yet, upon reflection, they're all good songs.
