I suppose that if the narrative of any of the songs that have been mentioned in this thread -- including its original subject, "Taxi" -- made you want to hear more after the first couple of verses, I'd call that song compelling rather than ponderous. To me, "Taxi" had little to say after Harry and Sue exchanged their "how are yous." Dan Fogelberg explored the same general them in "Same Old Lang Syne," which I listened to fully the first time I heard it because I wanted to know if Dan and his old lover finally got back together. The narrative of "El Paso" unfolded perfectly and grabbed the listener right until Felina's last kiss. (And five years later, Jay and the Americans had a huge hit with their Southwestern story-song "Come a Little Bit Closer."
As for "Wreck," the title took away most of the suspense, but if you weren't familiar with the actual event -- which I wasn't -- Lightfoot told the tale skillfully and in great detail. If you're not into folk-style storytelling, the song probably bored you, but I can see why it's still played today on the dwindling number of classic hits stations that still play a lot of '70s titles.
BigA: I'm curious about your assertion that the mid-'70s, when "Wreck" was a hit, was a down period for Top 40 radio. Are you saying that such memorable songs as "Rock the Boat," "Sister Golden Hair," "Philadelphia Freedom," "Brother Louie," "Tonight's the Night," "When Will I See You Again," "Angie," and so many others were all merely "turntable hits," that few people ever bought the records, and that their presence on radio in the 2020s is strictly the result of programmer ego? Sorry, not buying it.
