The other question that puzzles me - can something actually be called a 'hit' if it doesn't become popular with the laity, or commercially successful, until 300 years after it's written?
In any case, I wouldn't even say Canon in D is popular with the laity, can't be described as commercially successful since I don't think he made much money off of it, and it is certainly not even close to being one of Pachelbel's most popular compositions among those in the classical music community. In fact, it's probably one of the most reviled - if only because it is sooooo overplayed due to the fact that it became very trendy to play it as a wedding processional in the last part of the 20th century. Thus its familiarity and, to an extent, its popularity grew 'among the laity'.
Now, if being extremely overplayed, excerpted, rearranged, and reiterated constitutes a 'hit', then Canon in D certainly qualifies.
