Jeff played 5,441 unique songs on WMBR from 2015-2020, according to his playlist archives at www.track-blaster.com. (A playlist search lists 5,755 songs, but 314 of those entries appear to reference live sets rather than individual tracks.)
As a testament to Jeff’s never-ending hunt for new music, Jeff rarely played a song more than once. When he did, it was almost always a different version of that song. He played: One song, four times; Eight songs, three times; 87 songs, twice; and 5,345 songs, once.
