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.
