Song by Song is a track-by-track Tom Waits project with the shape of a long conversation and the memory of a catalogue map. Its basic promise is narrow, almost stubbornly so: take one song seriously, then take the next one seriously too. Over hundreds of episodes, that becomes something larger than recap. The show builds a running argument about Waits as songwriter, performer, actor, image-maker, collaborator, and constructor of strange little worlds. The tone is relaxed, but the attention is close. A discussion can begin with a favourite line and end up in beat poetry, gospel rhythm, brass arrangement, period atmosphere, music video costuming, or the difference between a studio take and a live version. The hosts are comfortable disagreeing. They also know when a side path has made the point clearer rather than just longer. That gives the show its best quality: it sounds like close listening happening in real time, with all the caveats, jokes, corrections, and sudden changes of mind left intact. Recent episodes show the format stretching beyond individual album tracks into final-season specials, including recommended starting points, ranked favourites, music videos, and reflections on making the show for eight and a half years. Those specials make the scale of the project visible. They also show how much of the pleasure comes from comparison. A song is judged against an album, an era, a film, a stage persona, or the mood Waits seems to be summoning. Guests bring useful outside angles, from video knowledge to personal associations with songs and places. The show is not a slick primer. It is better for listeners who enjoy detail, argument, and affectionate exasperation. It can praise Waits for being hypnotic, joyful, or deeply odd, then turn around and question whether a particular object actually works. That balance keeps the fan service honest. Song by Song is for people who want criticism that still sounds like fandom, and fandom that has done the listening.
