Anthony Easton has been doing this project sorta thing where he asked people to tabulate what they listened to most frequently last year (as opposed to their official critic-minded aesthetic- evaluative Best Records of 2006 end of year type thing), this obviously including all the stuff that wasn't recorded in 2006, and not just reissues but just old stuff you dug out and played to death. Naturally this is hard to do with any scientific accuracy, given the nature of memory (bit like trying to remember meals you ate in February), but this was my guess of what got the most sustained play. Not totally sure why Anthony has rendered it as a Mixtape though, as it's a Top 10 Chart--or two charts, one for albums and other for individual songs.
