How old must a song be to be considered and "old song"?
Only songs released in the past 18 months get classified as “new” in the MRC database, so people could conceivably be listening to a lot of two-year-old songs, rather than 60-year-old ones. But I doubt these old playlists consist of songs from the year before last. Even if they did, that fact would still represent a repudiation of the pop-culture industry, which is almost entirely focused on what’s happening right now.
