Well, according to the authority on Yacht Rock, linked below, you're both wrong and right, lol. Generally, the early Steely Dan work from the first 2 albums, including Reelin' In the Years and My Old School, are not considered YR, given that they're earlier and a bit edgier/rockin (in general), while the later albums from Katy Lied (4th album) until the end (which include all the other songs listed, iirc) are generally considered YR, partly because of them being after 1975 and partly due to their generally cooler/jazzier style - and Katy Lied featured Michael McDonald the evil genius of YR, lol. Pretzel Logic (3rd album) has songs that score right on the edge of YR, including Rikki Don't Lose That Number and Any Major Dude Will Tell You. As someone who was a big fan of SD's early albums and not so much the later ones (with exceptions), I tend to agree with the scoring.
