Hopefully it was Totale's Turns, lo-fi decades before lo-fi was a thing.What's wrong with Lambchop?! I'd never put them in the category of audiophile discs!
I walked out of an LP12 demo at a dealer in Leeds because he wanted to play Fairground Attraction instead of the Henry Rollins Band and Fall albums I'd taken. My perception, based on going to shows recently-ish is it's got worse with DK, Norah Jones et-al.
I too got the snob treatment demo'ing an LP12, at Jeffries in Brighton, mid-80s. I wanted to play Joy Division's Closer, which in their eyes 'wasnt very dynamic' and they switched it for some awful 'female vocalist' recorded well but dull as dish water.
On the topic of top songs recorded well, nothing for me beats the 12" of ShipBuilding by Robert Wyatt. Epic.
